I contacted INNdulge and gave them the following dates for this December (16-21). My ticket with AA is cancelled and will re-book later on.
Since December is off-peak, I got three days for my previous two-day reservation. I booked two more days at the off-peak rate, for a total of five days. I'm hoping that the average December temperatures of (70° / 44°) will be warm enough for the pool, otherwise I might find myself in the hot-tub trying to find a good spot...
