Just outta curiousity, why would you bother going to a foreign country if you wanted American lodging and surroundings?
I've been baffled by this since my first trip to Budapest, and have never received a reasonable answer, imo. The standard response is usually something to the effect of, "I like to stay in a comfortable place that I'm familiar with and will live up to my expectations". It just doesn't wash. Help me understand, won't you?
For the record, I always stay at Holiday Home in Prague
www.holidayhome.cz and have found it's location, comfort and accountrements better than anything Conrad Hilton or any other American hotelier could offer, at a very reasonable price.
Whatever your ultimate decision, I hope your stay in Prague is a good one. It's one of the best and most beautiful cities in the world.
Cheers.
