Really depends on when you go,which level hotel & dining you want, & what kind of a discount you can get.
In May, taking DD & her BFF we have 2 rooms standard at Pop, with regular
DDP, upgraded the tickets to 7 day hopper tickets, rooms on the 4/3 deal so it will be $1788.86 per reservation so that works out to $127 per person per day for room,food,park tickets. Probably another $100 person for misc. spending (alcohol, souvenirs, etc.)
In Sept, taking DS & his BFF, we have 2 rooms standard at Pop, Free Dining, 7 day hopper tickets...since I didn't book 2 rooms on the bounceback (added the extra people later) to get son & BFF included on Free Dining we had to add their names to our room, so we have to pay the surcharge for 2 extra adults in our room, and then we added a room-only reservation for them so we don't have 4 adults crammed into those small Pop rooms (the room-only reservation has a
AAA room discount.) But even with the over-charges on our room, it's still going to be a lot cheaper than the May trip...$2543 total, or just over $90 per person per day for room,food, park tickets. Same as before, probably another $100 person for misc. spending.
