Can we go to and stay at Storm along Bay after we leave the room on the last day (we reserded BCV for family the following week and were not able to get reserves for us so we will be at BLT)
No, you need to be booked at BC. If you were at BC, then check out, you can use the pool ONLY on that check out day. Make sure you have your magic band to get in the pool area.
Does your account still show that you were staying at BCV after check out?
We had checked out of BWV, moving to VGF. When I returned to BWV to pick up DW, the gate guard scanned my band and only saw the VGF reservation, not that we had stayed at BWV.
