time 4 peas

Hello everybody. I am wondering if anybody has an answer for me on this question. When you get enough points using your bank of America card to receive a free cruise is this just for one person and you pay for your companion? If that is the case can you use points for a shorter cruise and points for a companion on the same length cruise? Thanks in advance if anybody has the answers to these questions. I have scoured the internet and just can't find out either way.

I am on the Enchantment of the Seas 7 night western Caribbean cruise Feb 17 through 24th. I have heard the tender process can be time consuming and Belize city is less than safe. With that being the case I would want to book an excursion directly through RC. I only see 2 options and they are both for cave tubing. I really would like to see a Mayan ruin. Is it possible an excursion like this could be added later? If anybody has taken this cruise recently please let me know what your options were.
