Mine are rather boring...

1. Expensive Internet (Again, worst deal in the most expensive hotels, it seems)
2. Poor Internet Connections (it's not that hard to use wifi, someone always implies i have some kind of "setting" problem when I call about it - oh wait, no, the router is out in that part of the hotel, etc. At least I have always been able to get a new room for a nonworking internet connection)
3. Internet on a set time, rather than a 24-hour cycle, inspiring one to wait until some arbitrary hour to start using the internet or else pay a full day for 2-3 hours of usage in some locations
4. Not enough power plugs/power plugs accessible only by the desk.
5. The little coffee pods - I know they're more hygienic than regular filters but it's always a process to get more of them.
