Like I said, whether 2k is a lot of money for extras really depends on what your family expects out of the trip, how often they can do it, what's available nearby, etc.
For us, for example, we have NOTHING similar, or even within a days drive, or even TWO days drive, for us out here, so we get just one chance to do many of the things available at the World. Nor do we have a
Disney store within a days travel, (or even a decent ANYTHING store!) so if we want to see something before we buy it, disney it is. How can we blow 2k? Easy:
Star Wars items only available at the World, that we are aware of: about $200 (cups, mugs, shirts, limited edition items, we're huge SW nuts and can never get to a convention, this is the next best thing)
One framed autograph of a voice actor/character in a Disney movie, with plaque that matches the others we have: approx $400 depending on the character. This is our big, special thing every trip.
Christmas shopping for family for the next few years: approx $500. The only stores we have within a days drive are Wal Mart and Target, so it is our big chance to get unique gifts. That $500 covers extended family for a VERY long time.
T-shirts, embroidered hats, and other incidental souveniers that most people would buy: approx. $150
More clothes for school, work, etc since the selection out here is awful: $200
Tours and spur of the moment special things (pony rides, hay rides, etc): about $200
Shipping for packages (since we can't take most stuff on the plane due to weight restrictions) and leftovers for emergencies (stuck at a park and need a cab, etc).
Next time we will be able to go to Disney due to work schedule. taking DD out of school, and expected DH doctor trips and physical therapy: about 6 years from now. So yeah, 2k spending money for some people is WELL worth it.
