I booked mid-July...called the direct # to the Dolphin 1-800-227-1500 and applied the ALLEARS code. I had been told that there would be a rate change on the 25th, to 269 for our last 3 nights. I said o.k. as I needed the room and would keep trying to get a discount. When my confirmation letter arrived from the Dolphin it only showed our Allears rate and was only dated thru the 25th. I called back to make sure our full dates were on our ressie and was told that since there was a rate change that may have goofed up the conf. letter, and I was quoted the rate of 169 starting on the 25. As you can imagine, I was thrilled and confused at the same time. I asked how I rec'd the lower rate, was told it is an Expedia rate and that the Ressie clerk applied it.

I called several times to verify, and to see if I needed anything as I have never booked thru Expedia,and was told no worries, 147.50 thru 12/24---- 169.00 12/25,26 and 27.
I did see on the Expedia site a rate of 140 available thru 12/26, changing to 269 on 12/27...but that is thru them, not the Dolphin so cancellation/payment etc is different...great rate tho. I am keeping my orig as they both average out to the same per night and have a lakeview w/Allears, not standard like expedia, and I can't risk the paying up front situation.
Good Luck....I also saw Ent rate of 149 back in July (when I booked) thru the 24...not sure if still available, and try AP...but call the hotel direct, I think you will have the best service that way.
