MB Activation

We are staying off site and have never used MBs that came with a room reservation that was never used/canceled. I can see them on my MDE account as active. Will we be able to enter the park with them no problemo? Or do we need to go to guest services or DTD to activate?

I ask because I read about resort guests having to activate their bands before they can use them in the parks. (I plan to take our park tickets as backup first day. But would prefer to use MBs for convenience, FPP, etc).

Usually the only activation that is necessary is when using Free Dining credits. As long as they show active and your tickets are linked it should work.
