I can't give you any insight on the Holiday Inn you asked about, but I did recently fly into FLL for a Miami cruise. It happened to be on Carnival that time, and yes, there were shuttles for several cruise lines there going to the Port of Miami. I did not even book in advance, just walked up and signed on there. I don't specifically remember if RC was there, but a quick phone call to their customer service will answer that. That is how I found out about the one for Carnival. (If you booked through and agent, they should take care of getting it for you. I bought from SkyAuction and they do none of that.) I think I paid $16.00. Taxis were quite a bit more, I just don't remember how much. This was on a large comfortable motorcoach and I hate taxis, anyway. (We have found that two women going on a 7-day cruise, we can barely get our luggage in a taxi - ha!) I hope you get more info, but I noticed there were no other responses, so I hope this helps.
