book the room and watch the rates, bit early for July yet, they will probably not announce a 7 for 4 until about March, although you never know. Annual Pass discounts where very good last year, and i booked the stay 7 pay 4 for $140 + tax
I agree - make your reservation to secure your room - you only have to pay a 1 night deposit, which is fully refundable up to 5 days before arrival. YOu can then change the rate if it comes down
