Depends on the trip...I go to Disney about 5-6 times a year, and the number of photos varies by season and purpose of trip. If I'm traveling with family or friends where photography isn't the primary focus of the trip, I'll typically take 300-500 total photos in a 4-5 day trip. If I'm there specifically for photography (either a solo trip, or when I go annually with a photography/Disney board group), the number increases drastically, and can be in the 2,000-3,000 range over 4 days. Much of this is also attributable to the fact that we'll be shooting shows, stunts, animals, etc which require a lot of continuous shooting...of those, I'll usually get home and immediately cull 50% or more before I even start editing - getting rid of duplicate or flubbed shots, maybe keeping 2-3 shots out of a burst of 7-10.
Season also affects my shooting...winters and cooler weather I typically shoot much more than hot, humid summers. My typical May/June trips are in the 300-500 range, whereas my typical Jan-Mar trips are more like 700-900, even with family. It's a lot more pleasant to head out at night after everyone's worn out and back at the room and take some tripod night shots when it's nice and cool out!
I just returned from Disney yesterday, from a 4 1/2 day trip. Weather was marvelous - highs between 65-70, lows in the upper 30s to mid 40s...and crystal clear blue skies and sun. I was with family, but the weather was so pleasant I was out shooting even around hotel grounds as late as 1am. I shot 940 with my DSLR, and 275 with my mirrorless...this is higher than I typically would shoot on a non-photography-centric trip, but the cool weather made it easy to do!
