Yes, we are doing a split stay!
We're at Pop for three nights and got the kids 8 day tixs free with the kids stay/play, then we switch over to the BC for 4 nights using our 40% room only discount
We arrive at Pop on 9/13. On 9/16 we plan on checking out of Pop early and taking a cab over to the BC. We'll check-in, have an early breakfast at Cape May then the kids will go on the Albatross pirate cruise from the YC while DH and I check out the resort

We'll hang at the resort and later that day we have PL ressies and MNSSHP
I did plan more of our Epcot time towards the BC part of our stay and more down time so the kids can enjoy SAB, which is a big reason why we chose BC.
DH, the kids, and I are beyond excited!

Without the great discounts we wouldn't have been able to swing the BC so I'm like a little kid, I'm so giddy about it, LOL
