Forgive me if this has been discussed before. Last night (Sunday) my wife and I almost booked a stay at the Ritz Carlton, Key Biscayne. We decided to wait until today (Monday) to confirm we could take those specific days off. I went on Marriott.com to book it and the price of the room for the same dates went up $200 per night, which is now out of our price range. Just checking to see if anyone has experienced this and if they have a recommendation on the best day of the week to book.
