I have a reservation at a Residence Inn in Orlando for March using code LPR. Got a great rate for a two bedroom suite of $129/night. Unfortunately I jumped the gun and rather than arriving on Saturday as I reserved I am arriving on the following Tuesday ... still staying until Friday. When I called the 1-800 number they told me they could change my arrival date but the rate jumped to $229/night (same as it shows if I book a new reservation for the new dates with the same code). I said that wasn't what I wanted and they recommended I contact the hotel directly. When I did the hotel said there was nothing they could do as the rate goes up the fewer nights I stay ... as they are an extended stay hotel. I thanked them and left the reservation for now ... but went on the marriott website to check out their contention that a shorter stay would cost more. When I compared my previous arrival date (6 days) with my new arrival date (3 days) the 3 days was actually $20 per night cheaper ... flying in the face of their explanation for not being able to do anything. Any suggestions for strategies to have them just drop the 3 nights I don't need while maintaining the rate?

Thanks so much....
