Very happy for you but the OP's situation is different. You never know where the World Series will be played until you get down to the two final teams. OTOH, The SuperBowl city is known years in advance. The NFL et al booked rooms long ago and that's what makes this situation different.
Sorry OP, for the future may be better to book long in advance with cancelation privileges than find yourself in one of the worst hotel situations possible.
