Speaking as someone who's been aboard at least one ship of every class from Royal Caribbean (except the new Oasis class), I can't think of many places that such an event could be held.

An FRC event needs at minimum:

A 30x60 (and more realistically 40x70) area to put the field.
2400sq ft of pits. (24 teams x 10x10 pits)

UNLESS

You're only running half an elimination bracket (Semis/Finals), in which case, you only need 12 teams.

Studio B (The ice rink) on Voyager and Freedom class ships might work. Its physical dimensions would be close as far as putting an FRC field on it, the problem becomes where do you put the pits. There is a stage, and one of the 3 banks of seating folds away, so you could probably fit a few pits (i would think no more than 16) in those two places.

The only other place I can think of would be the Basketball court. This has a few issues of its own. Its open-air, so the elements could play a role. The field, plus a couple teams could fit on the court, and the area around the court could hold some pits, but I think no matter how you slice it, you're into non-10x10 pits. There just isnt enough free space anywhere on the ships.

In addition to all of that, you have the issue of storage, of tools, robots, carts, field, etc, for the rest of the cruise voyage.

@OP: FYI, Majesty of the Seas does NOT have an Ice Rink.
