Firstly, thank you for your reply. Just to make sure I'm clear.
First two days we are at a Room Only at Beach Club (I added this on the front end of our trip as it was a great 'magical' deal). When I booked this room only deal, I didn't want my dad to know as it was a surprise, so I couldn't use my dad's MDE (the one that we always use to travel on) so I created my own MDE account. No tickets or anything - just going to relax and enjoy SAB and Boardwalk.
When we go to POFQ for the next 13 nights, we are on FD/tickets under my dad's MDE.
Same people going on both trips and same people listed in both MDE accounts.
So are the bands still interchangeable? Will the tickets from POFQ trip end up on my BC magic bands? Does this mean if I wanted to, I could access the tickets from POFQ stay while at BC? I don't want to, but now I'm curious. I'm learning a lot about the Magic Bands and MDE still. We go every year, but have only used the MB's once.
Thanks for your advice!
