Did you try - http://code.google.com/apis/maps/documentation/places/#PlaceSearches ?

It looks like a normal webservice, you can just post a request and it should give you an XML / JSON list of all the hotels around you ..

From the website -

Request = http://maps.google.com/maps/api/place/search/json?location=40.717859,-73.957790&radius=1600&client=clientId&sensor=true_or_false&signature=SIGNATURE
