I’d vote CCV, but in terms of the broader SAP+ ‘portfolio’ you are building, there needs to be room for a monorail resort.
In which case I’d argue CCV + Poly.
But that’s just because I don’t terribly find BLT appealing thematically. Which is weird, I almost unequivocally like all the resorts otherwise.
Poly though is still a bit dependent on things like
points charts and availability. This would lead me to say if you aren’t rushing to add all at once, CCV first and then see how the next 6 months shake out.
