Quite a few things...
1. I want the 11-month booking window. We are 1-bedroom people, but I thought there are times we might stay in a studio if we want to save the points for something else. It's not impossible to get a studio at 7 months, but I just don't want to risk it. I want flexibility.
2. Deed expiration/Low MF/Future plans - Our other home resort is a 2042, and if we want to continue to be members after that, obviously we'll need to own something else (and we aren't very interested in buying direct at new resorts). Since BLT will be part of our split stay pretty much every trip (we love the convenience to MK), why not make that our 2nd home resort? The low MF is also attractive, very manageable. If it doesn't work out in the future, I can always sell it. If we do end up keeping it, the plan is that as we get closer to 2042 I will start adding on smaller contracts to build up our BLT ownership. That way, I have plenty of time to look for the right contracts, we won't have any gaps between memberships, and we don't have to shell out a large sum of money at once to buy a bigger contract. The resale value for BLT by then should also be lower. Of course I know nothing is guaranteed, but for now my plan/logic make sense!
3. Future refurb - BLT is due for the big refurb soon, and seeing how popular BRV became immediately after the refurb, FOMO kicked in!
