Would definitely grab the standard rooms at Pop if that is where you want to stay, and keep an eye out for preferred to open - people do change dates and resorts, so things can open up - or choose another hotel that is a second choice, and watch for Pop rooms. Since you are just putting down a deposit, it can't hurt to have a room if you definitely want to go at that time, and switch later if you can. You can also try breaking up your week - sometimes you can get 2 reservations when you can't get the whole week, and then ask for them to be linked, like Sun - Wed, and Thur-Sat, or your first night standard and rest preferred. We had trouble getting all our days last Nov., and did three nts standard/1 nt preferred (no standard available) at ASMu, and last nt at AoA ( wanted to try LM room so that was planned when we added another day). We actually loved Broadway location in standard so much, we opted out if preferred switch for last nt there, and got a refund, which worked out as they needed the preferred room (guess had overbooked) and left a message on phone in room (that we totally missed ) asking us if we'd like to stay in current room.
