My biggest complaint is the dispairity in elite levels..I am "Diamond VIP" at Hilton..and only "Silver Elite" at Marriott..I average about 30 stays a year at Hilton and the same at Marriott..but,at Marriott I need 50 stays to get the same elite level Hilton gives me for 28 stays..Yes,I do prefer the Marriott brand but I will choose Hilton for discretionary travel not because I like them more,but because I recieve superior elite benefits..@:-)
