Unless the actual handset is compatible with both the US and Europe (tri or quad band) just changing the SIM would do no good
Which is why if you ever travel it's always best to get a quad band phone, unlock it, then if traveling you just pick up a local SIM where ever you go, especially as now most countries have them cheap and easy to get. Saves one an absolute fortune in roaming charges
As to the hotel charges, for the wife to use her UK mobile with UK SIM in the US the charges would have probably been even greater than the hotel charges, both for incoming and outgoing and those charges would have been the same even if she was calling the very hotel she standing in
