There are 8 of us going on this cruise; my husband and I, both my adult sons and girlfriends, and my husband's daughter and husband. We sailed on The Allure back in 2014, so it's been a while. This will be our 5th cruise with RC. (We've sailed on just about every cruise line!) Tuck: We sailed with RC last December and I thought there was just one formal night on their 7 day cruise, but I've been reading and it says on Allure, there's usually two, Day 2 and Day 5.
