This trip will be actually pretty reasonable since we bought an annual pass and a non-expiration pass last year before our wedding/honeymoon. We're two adults going Sept. 19th - Sept. 29th. 7 days at Disney parks, 1 day at Universal, and 1 day at Sea World. Our last trip was fairly expensive due to it being our wedding/honeymoon.
Rented points to stay in a BLT studio for 7 nights: $1,100
Half of the AP and half of the 10 day non-expiry ticket: $600
We bought a TIW card last trip so with getting 20% off our meals and buying 5% off gift cards from Target, I usually overbudget at $100 a day for us (though we typically spend $75-$80 a day, which will be even lower at 25% off). We do two TS meals a day at Disney, but typically just CS at Universal and Sea World: $1,000 for ten days
3 nights at Wyndham Bonnet Creek: Free from parents
Flights: Free from Southwest points (ok, $69 for the annual fee)
We have Sea World annual passes (I don't really factor this in as we go to Busch Gardens Williamsburg/Water Country all the time so we get lots of uses out of our Platinum passes) and a day left on a pass to Universal.
My parents are going too and are driving so they'll be our transportation outside of Disney
We don't buy souvenirs, but I budget $150 for misc. stuff.
$70 for airport parking.
And the biggest budget buster: $800-$1,000 to board three dogs for 10 nights. They could stay at a room in BLT for that price!
Oh, and two tickets to the Halloween party : approx. $120.
Disney total: $2,820
Transportation/Other stuff: $1,289
Total: $4,109
That's almost always overbudgeting by about $300. Plus, we'll have about $150 on our Disney Rewards card.
