Before the Trip
RSSC has a fairly good web presence, so we were able to research the details of the trip right on their website in addition to Cruise Critic. At the appointed day, we were able to select our excursions and dining reservation (1 each at Signatures and Prime 7 is allowed). I had no problems reserving the excursions or the dining, as I made them the very first day they were available.
The excursion information is relatively vague on the RSSC website, although they try to at least give the cruiser an idea of the length and physical exertion. I found Cruise Critic also to be scarce in information on the RSSC excursions, so we felt like we were going into them a little bit blind.
