I am doing two back to back cruises next May. Two separate bookings with second booking a guarantee. Will I be able to have Vista customer service hold my luggage while I do an excursion on my check on day for my guarantee or will I have to spend that first day going through all the check in procedures for a second time? Thanks in advance. I have never done a back to back before much less one complicated by having a guarantee. I am still a year out and am hoping to rectify this situation
