I would definitely take the camcorder! We always have, and we're glad we did because we watch our Disney tapes all the time!
If you don't want to carry it around all the time you can do some of these things:
1. If you're staying onsite, and taking mid day breaks, either bring the camcorder with you in the morning and leave it at the hotel for the afternoon, or leave it in the morning and bring it in the afternoon. That way you don't have to carry it all day.
2. If you have any adults or older kids going with you, take turns using the camcorder, so one person isn't using it the whole time
3. If you're bringing a bookbag, you can just store it in there if you don't feel like carrying it anymore.
But I would bring it, because it is definitely worth it!!!
