I'm going to Orlando for a week in October, this is my breakdown of costs for 2 adults only (everything includes taxes/fees and are rounded up to the nearest $5):
Airfare from Honolulu (using miles, only had to pay a small fee), $20
Rental car for one week (using discount code), $145
2 nights at the Hard Rock Hotel, $390
3 nights at Pop Century (w/ a discount code), $165
2 nights at AKL standard savannah view (w/ discount code), $340
Universal tickets 2-day w/ 3rd day free (military discount), $190
WDW tickets 5-day hopper (NO plusses) (military discount), $490
Total fixed costs: $1740
Variable costs include things like:
Mousekeeping tips, $25
Food (I have a good idea of where we're eating, but I usually estimate $100-$125 per day for the two of us since we tend to eat at a few of the more pricey restaurants), $800
MNSSHP tickets, $75
Souvenirs (we tend to take care of some of our Xmas shopping on these trips), $1000
Gas/tolls, $40
Total budgeted variable costs: $1940
So that would bring our total budget to $3680, for two adults only.
But like everyone mentioned it really depends a lot on your preferences, particularly with the hotel and how you eat. Our airfare is basically free, but unless you're using miles, you'll need to budget for that.
With the hotel, had we chosen to stay the entire time at Pop Century, with the discount it would only be $400 for the entire week. What I try to do also is pay things off slowly so I don't have to pay a bunch of money at one time. So my hotel is almost all paid, and I got my Universal and MNSSHP tickets. Will be getting WDW tickets soon. And I've started saving dollar bills for Mousekeeping tips.
