Because Las Vegas is unlike other destinations, you also hear some truly unique complaints about it. Some of my favorites:
Service was really bad. I had to wait xxx minutes for my FREE DRINK.
The hotel was completely full. No free upgrades were available. So I got stuck with the room I paid for.
A. You have to pay to use the gym or for internet access. B. The hotel charges a resort fee to cover use of the gym and internet access.
Amazingly enough, many of the same people who used to complain about A now complain about B.
Only guests of the hotel are allowed to use the pool.
The hotel is tightening up on comps, so they wouldn't pay for all my meals.
They don't allow 5 adults to share a room.
I could go on but I don't want to bore you. And I'm sure others have their own favorites.
