They run an on board series of competitions, so one lucky guest wins a significant cash prize too. I am sure you will have to arrange your own insurance and spending money. Find out what is included in the prize, and what you may need to provide yourself. Hopefully, tips will be inclusive.
I have not won this one, but I did win a trip to the 2006 world cup final and a weekend in Vegas, so I know how other groups deal with such things. For the world cup trip, flights, accommodation, and the tickets were provided, but insurance and some extra spending money was down to us. We more or less did our own thing.
For Vegas, there was some VIP entertainment laid on, but we had a bit of time to ourselves. The purpose of the trip was to meet and entertain a group of VIP players, so things were more organised, and this will probably be the case on the cruise. Flights and hotel (in the casino) were provided, but spending money and insurance was again down to us.
In the case of the FL cruise, their news section provides reviews of past events, so you can get some idea of what to expect.
If it all looks to be too much, you may like to donate your prize to another forum member
