Item that was unique;
I have run into a few Marriotts and Crown Plazas that have detailed dialing instructions and a listing of local on-line services access numbers, saving me from making a call.

Items that disturb me;
Electronic keys that don't work when you first get to your room.

You'd think that hotels in a chain would be consistent with the use of a 8 or 9 for local calls. Seems that one week it's an 8, next week a 9, then a 9 back to an 8.

A/C and heating units that don't/won't consistently work.

Phone lines that are toooo short to reach the business desk (NOTE: Fairfields are nice and looooong!)

Hotels that won't drop your paper at your door and then make you run down to the front desk.

Maids that take your soap and half used shampoo each day and also ones that don't replace the used bathroom linens with new items. Seems that they must think that one only uses one towel and washcloth a day.
