It's not just the single price of the hotel according to my clients, they are asked if they want to be part of the program, and Chase has set a threshold basically on what the commissions are vs. the chargebacks against the hotel for those extra benefits, and it varies by property as to what they are charging. So if a hotel agrees to give all the extras for free (which some do, hoping that will draw in more customers or bigger spenders, etc...) then their threshold would be lower than say the St. Regis saying they will charge $80 for the 4pm late checkout if it is taken advantage of. Places that opt to give away all of the benefits will be seen while at much lower price points, or the ones that are going to charge Chase for the space available upgrade at a certain amount of money as well. It works something like this formula (I don't know the exact formula, I just know the general structure. Room Cost x room commission rate - extra property benefit costs including onsite credit (which may be paid jointly or solely by chase), cost of breakfast (at negotiated rate for that property, room upgrade charges (negotiated costs with property), early/late checkin fees (negotiated with property), and these can vary widely from region to region or hotel to hotel, with some hotels giving it all to chase just to be part of the program, and others charging Chase for everything extra.

Based on what you are saying about the hotels in Vegas and Orlando, those properties are probably giving Chase all of those extras just to be part of the program. A sign to me that they are looking for more business, than other properties than are going to bill back what ever amount the onsite credit is used to Chase, charge $40 for everyone they end up upgrading, and charge $10/person or more for breakfast back to Chase.
