No it isnt too late. You can go the day off if you like but if you want the benefits of the poker tournament and the free room you gotta book with the IP and post your name in the list of ALT for the poker tourney since its already full.
1. Please call 800-800-2981 (group room reservations) between 9-5 PST with your name, address, and credit card to reserve your room (the RX will be paying for Friday and Sat night and your card will not be charged). Make sure to mention you are with either "Therx.com" or "The prescription." You will also get a discounted rate of $69 for any additional nights.
