I have a large family group of 26 going on a cruise. Our booking window is coming up soon and I’m trying to plan our cabana rentals. We have some concierge guests and non concierge guests. I was thinking of assigning my older kids (concierge) to the cabana next to me with the grand parents (non-concierge). So, since the adults in that grouping are non-concierge and wouldn’t be able to book the cabana as early, can the 15 year old “book” the cabana?
