Knowing how much money to take to Florida can be a minefield, and I don’t think that there is one set answer for this. I set aside £1,500 (about $2,300) when I went in 2012 but I did buy myself an iPhone and had about £300 left over. I go absolutely mad with shopping when I’m over there – I literally wait for my trip to Florida to stock up on my favourite make up (MAC at the outlets), Converse (which I always end up selling despite trying to convince myself that I am a Converse kinda girl), Wilton baking supplies, random crap from Dollar Tree, so many sweets and much (much, much, much more). I bring two suitcases home. When I went with Tony last year, we both brought two suitcases home as we’d been buying a lot of wedding things.
Parking at the theme parks runs at $14-$15 per day (around £10). If you visit two theme parks from the same company on the same day (two Disney parks, two Universal parks, etc) then your parking is transferable. Some of the theme parks let you park for free from around 5pm, although this really is hit and miss and won’t apply to Magic Kingdom. If you’re staying at that resort then you get free parking for your stay.
Eating out can be done for as little or as much as you want. A great money saving tip is to fill up at a breakfast buffet in the mornings, and these generally keep you going until dinner (dinner being the evening meal in this case), with perhaps an ice cream or something to tide you over. You can also take snacks with you into the parks, and if you’re very prepared, you can even pack a full on picnic to leave in a cooler box in your car. You can also sign up to restaurant’s mailing lists (here’s a handy list for you to sign up to) before your departure and they will come with money off coupons. And there’s free coupons in the weekly paper (Orlando Sentinel).
