I do holiday in the USA every year- twice this year but short breaks not main holiday. We go to Asia for 2-3 weeks a year plus a couple of Europe trips.
I find that service in the USA is very weak compared to Asia and recently most European destinations who now have lots of great enthusiastic staff from the former eastern bloc countries.
Plus the endless tipping in the USA is a total put off. Just charge one price to include service. I spend 700 usd a night on a room and it costs at least 50 usd to get in and out of the hotel. It's a pain.
