Our trip costs vary greatly from one trip to the next (2 adults, no kids). Our upcoming trip in September we rented points to stay at BLT and I bought my husband a 10 days non expiration pass last trip back in June 2012 before the prices went up that he only used 3 days of and I bought an annual pass and a Tables in Wonderland card.
* 7 nights at BLT (we're also staying 3 nights at Wyndham Bonnet Creek beforehand, but we're using my parent's points for free): $1,100
* Free flights through points we accumulate through our Southwest credit card.
* Passes were paid for last trip
* We have platinum passes to Busch parks so we're going to Sea World for the day
* We bought 3 days passes to Universal from Costco in 2011 that we still have one day left on
* I budget about $1,000 for food for ten days as we generally do 2 table service meals a day (sometimes just one a day, depending on where we are). We don't do the dining plan and with the card we get 20% off. We also don't usually get appetizers/desserts with meals and we don't drink alcoholic drinks. Realistically, we'll probably spend around $700-$800, but I'd rather be prepared. Oh, I also buy gift cards from Target for our dining with my Target card for 5% off.
Are we including dog kennel costs? 'Cause that's about $600 more for two dogs...
I typically only budget about $100-$200 for souvenirs, but I end up taking most of it home.
So if we're including dog kennel costs: approx. $2,900 budgeted for and probably $2,500 spent.
ETA: My parents hate flying so they decided to drive down (they also rented points to stay at BLT). So that saves us money by not having to rent a car.
Our wedding/honeymoon trip in December 2012 for 2 nights club level at the Poly and 7 nights in a one bedroom at OKW, plus passes, flights (free through Southwest), dog kennel, and food was about: $4,500.
