Generally, the Haversine Formula is the best one to calculate distance between two points, given the lat/long of both the client and the hotel. See http://en.wikipedia.org/wiki/Haversine_formula for more information.
SELECT acos(sin(radians(P2.latitude)) * sin(radians(P2.latitude)) + cos(radians(P1.latitude)) * cos(radians(P2.latitude)) * cos(radians(P1.longitude) - radians(P2.longitude))) * 3963.1 AS distance In CakePHP, you can implement that as a calculated field.
