hehe ya sounds like you have allot more gear to carry around the me. I usually just rent a locker to store the camera bag tapes etc. I drop the battery charger and extra battery off at guest services for charging while I am away then i carry the digital camera, and camcorder till I am done with one park then move on to the other and do the same process there
Most of the time I use a digital still camera w/ video capability. ( an olympus c700). The quality of stills from most of the camcorders I have seen isn't that great.
I do take a video camera some times and make a point of using it but I don't want to be one of those people who miss the trip 'cause they are looking in a video camera the whole time.
