Okay. Thanks. So, that means I can at least check with them. I don’t want to miss out on a Bay Lake Tower room (which they recommend trying to reserve 10-11 months out), but I also don’t want to lock myself out of the possibility of staying in the Contemporary Tower if there is one! 
I contacted an agent shortly before the rates were likely to come out (if you look on social media for the previous year to your trip you can get a guess of when that might be) and she sent me the rates for our potential trip dates the day they were released. Totally understand not wanting to miss out - staying at BLT or Contemporary is on my bucket list.
