It will depend if you plan on going back to a hotel room during the day....
If I'm with my kids, I know we'll go back to the room during the day, so I won't bring the tripod early in the day. But if I'm not with the kids, I'll bring the tripod and rent a locker.
Lens wise, it depends on what you have! If you have an all-in-one (18-200 for example, for me the 28-200 for now), you could probably get away with just that lens and then a fast standard lens for dark rides.
I'd bring several memory cards, spare battery (or two), remote release (if you are bringing your tripod early in the day). Filters - the only two that really are of use now: circ. polarizer and ND. My 28-200 doesn't handle non-low profile UV filters, but I'll be changing out my regular lens hopefully before the end of April.
