We're debating going down to Disney World for a short trip (3-4 days) when LO turns 2 in October. Does anyone have experience going to the parks with a young toddler? Do you think it's worth it?

The trip would be with DH and also my dad and brother, so we'd have help. My dad really wants us all to take a trip together, and he's a huge Disney fan, so that's why we're considering it. Btw, this trip wouldn't mean that we couldn't go back when LO is older. I'm just wondering if it would be fun or merely exhausting.
