Summer Bay - Guests & multiple users

I noted in another thread that Summer Bay Las Vegas is issuing ID badges for owners. How does this impact guests and exchangers in for a few days?

The week I'm purchasing is for convention housing for my department and I may have a few other people rotating in and out during the week. Basically I'm trying to figure out if I'm going to have a problem with multiple users accessing the unit.

When we stayed at SBR in April, we were advised that owners will need membership cards. DH and I had our pictures taken and our I.D. cards were processed for our use next year. I don't know how guests or exchangers will be handled.
