OP here- Thanks a bunch for your advice.
After talking with the family we decided that a 2BR would also give us the flexibility to eat in the room if we wanted to. Or we split some QS meals if we want. We probably would do Chef Mickeys because it will have been six years since that one, and walking is a bonus. Having just stuffed ourselves on the DREAM I can not fathom doing the dining plan after that.
Someone mentioned the laundry too - and I had not thought of that so that would definitely be a bonus to do a few loads before we go home.
We are SSR owners not BLT, so I was hopeful that both options would be available if I called at exactly 7 months. We have always been lucky so far.
We just stayed at AKV Kidani and would do that if BLT was not available. We made a SSR treehouse ressie at 11 months out just in case because we have stayed there before and know that space would work - though not our first choice.
Having said all that I would be happy for a stay anywhere - it is WDW.
