how many hotels in us
I don't have a precise answer but I've got some interesting numbers that may help you out. According to Euromonitor there are approximately 106,000 hotel, inns etc in the US. According to Expedia's 2009 annual report they have 64,000 merchant properties (ones that connect directly to Expedia and not via the GDS) and 130,000 hotels total. I didn't see details by country.
