We ended up using the Marriott option. Dipped in the pool, had an extensive shower (very welcome after a full week of camping), had great complimentary food in the lounge (and some pricey wine) and managed to get 2 hours of shut eye. Price got down to $159 with CAA card, which was amazing value. Front desk said to not check out at 1 AM in case of delays/cancellations, which was a great idea. Checked out on the app after our flight.
