Not trying to hijack the thread, but we have a similar dilemma so I’ll be watching the responses here, and throw in another aspect to consider and hope that can elicit some opinions as well.
To the OP, we originally did what you were thinking, all at SSR, but realized maybe we were a little naive in our ability to book elsewhere at 7 months, especially studios. We have since thought of adding on at a couple of other resorts to have multiple home resorts for the 11 month booking, but also more points to upgrade to 1 br, for the space, but also the increased availability. I’d say as long as you don’t get any of the 2042 resorts you’ll be fine, although PVB, VGF, and soon CCV (going to $210 June 1st) will certainly fetch a premium going direct. Whether you get SSR, or one of the other lower cost options, only you can decide if you like those resorts. Also know you’ll likely be able to use those points to fairly easily book them at SSR at 7 months, maybe except on holidays, and at least for now.
We started with 75 direct SSR, added 175 resale SSR, and are now under contract on 100 PVB resale, all Feb UY. While on our recent BCV stay at the beginning of the month, we extended 1 night at SSR and did the DVC tour of the RIV (DRR not sure what we are calling it). My wife LOVES the resort and rooms, so we are considering adding on 75-100 there, but to add on there for a Feb UY you get no 2019 points, where in later months you do. Our dilemma, stick with Feb UY and forego any 2019 points, or change UY and get 2019 points to immediately bank into 2020? Thoughts?
