Stayed in many Travelodge hotels over the years,so these are my comments.

I think televisions MIGHT be on a timer(not sure if they are and how long it is)so the telly switches its self off after a certain time that it has been on.

Plastic water cups,glad they don't have these any more or even glass tumblers,we can use the china cups to have a drink.

Always put the kettle on the floor to have a hot drink which reduces the noise  level during the early hours of the morning.
Always take our own coffee,and what benefit do guests  get from taking the milk tumblers and also the sleeves of coffee and tea?

When hotels are being built and fitted out,13 amp plug sockets should be fitted to an outside wall,which reduces the "smack" from those 13 amp plugs next door.
Don't like carpets in the rooms,it can stink of literally any thing

If you are staying for a long time,how often should you have the sheets changed? how often do you change your sheets at home.

Do you change your towels at home every day

Rubbish bins,always take our rubbish into the reception area for disposal.

What I don't like is they allows dogs in any of their hotels.

Smoking can be an issue

Finally, toothpaste we always remember to take our tooth brush but forget the paste.,
just wish they would supply those small toothpaste tubes,but without those small temporary tooth brushes 

Don't get me going (today - I've not got time!) on hotel design. Interesting topic having done it, and learned from the experience.   

The article was more about guest behaviour.   Should you scoop up the freebies?  Should you take the towels home with you?  Should you notify the hotel of your expected arrival time?  What should you do with your rubbish?  Should you ignore staff, chat with them, ignore them?   Should you walk around in the public areas with bare feet?  In your jammies? In your Birthday suite?  If something's wrong, what should you do?

This reminded me of an experience that my late brother recalled to us on his return from a short driving tour in Spain when he stopped at a small roadside hotel for the night some years back.  After an evening meal and (he assured us) just a small beer, he felt quite weary and had himself an early night.
The next thing he knew, he found himself waking up having sleep walked, stark naked, two floors down in the laundry room of the hotel at silly o'clock in the morning with a rather unamused night porter glowering and him.
He checked out quite early that morning.

Calling hotel staff by name?  Positively creepy, and puts me in mind of TV^▸ (Thames Valley, or TeleVision, depending on context)/radio news where presenter and reporter feel the need to repeat each others' names, or an overenthusiastic estate agent or car sales person. I wouldn't do it in any other conversation.

Don't think I'd be comfortable staying at a hotel so posh that phoning reception to get my luggage carried when leaving is normal, unless I actually couldn't manage it myself for some reason.

I have a lifetime's supply (at least!) of free mini-toiletries thanks to my parents who always took them on principle even if they didn't need them. Unless I'm travelling very light I therefore tend to take some with me so I can leave unopened any small complimentary stuff supplied by the hotel to be used for the next guest.

You'll also find that people call each other by name at the start of films / new TV shows too.

As (former) hotel staff, it can be welcome to be acknowledged by name from time to time / as a person and to help you do so was suggested as a reason for name badges.  We typically had only one or two people on duty, and tended to introduce ourselves by name when we checked people in to help us be more approachable, and we used names in continuity - "I'm around until 9 O'clock this evening and [name] will be in tomorrow morning at breakfast".

I am staying tonight at the Giardino Del Geco in Brindisi. When I checked in Alessio and Cristina introduced themselves by name, and the information folder has a "meet you hosts" page with their names and picture too.  In talking with them, I would / do feel comfortable using their names in natural conversation. 

I do see the smiley face - but in practise it's a big "no, no" for a hotelier to leave items in the room from one guest to the next.  Even the water in the kettle is cleared out was part of our cleaning procedure.   

Occasionally I stay in hotels that have failed on this - for example I did not touch what must have been a previous guest's salami in the fridge in quite the most run down hotel I have stayed in on my current trip in Clermond Ferrand.    And there was a little water in the kettle here in Brindisi, which I emptied, then rinsed the kettle through before putting in new water from the tap. 

We (at Well House Manor) only knowingly failed to reset a room to "as new" condition on one occasion.  We were running a series of courses for a well known national broadcaster,  and one of our students asked "was [name] in my room last week?".   Oops, yes, and he should not have been able to tell.  Turns out that the clock / radio when switched on started on the BBC^» (British Broadcasting Corporation - home page)'s Welsh language service rather than a default; those clock radios also needed to be checked to ensure that there was no daily alarm enabled to wake the new guest at an unwanted hour.

Regarding the little bottles of soap, shampoo etc: if I've started a bottle I'll take part-empty bottle with me to use up at home, because I assume that the hotel won't reuse it.  Whereas if I haven't started it I'll leave it for the hotel to provide for the next guest.
