Well, last trip I ate at the Blue Bayou, that was the very first time in my life I had done so.... That was a splurge item for me.
Once in the parks I tend to just eat there, so I am not spending my time going back and forth outside of the park, and that can be concidered a splurge.
As for things, well, I don't buy a lot of things there, so when I find something I really want, I get it. I bought a few things last summer, but haven't purchased anything in the last 3 trips, so I guess I don't concider that splurging.
I think that the next big splurge I am thinking about is actually staying on property for a night, another thing I have never done, have thought of it a few times, but always opted for the difference paying for my gas to get there instead.
