many times Ive seen where a lower Cat Hotel rates are alot more then a Hotel with a higher cat . Cat # doesnt mean it will cost more, sometimes its just its location that gets it the hgher cat #, nor does a higher cat# mean its more luxurious

personally if Im using a Cat4 from say the mega bonus and a cat3 is better located for my purposes then Id simply use it there rather then stay further away in order to get a cat 4 Priorities is more Important to me then so called maxing out usage of a free night/s
