has EVERY little tip, photo, piece of advice you'll ever need to go to Disney. I've posted my trip info and pictures, and when you get back, contribute your experiences. ;>) It's a GREAT resource, and I've planned our honeymoon and first wedding anniversary WDW trips based almost solely on that web site (and the WDW FOR COUPLES book, of course!). We have no children, so I won't be of much help to you because we spent a near fortune on both of our trips.
However, I think I can say with some authority (my hubby is 32 but has the mentality of a 9 year old sometimes- that counts!) that you should really, really consider staying on property. It's worth it (even if you stay at the All-Star resorts, which I've heard the kids love) because:
It's frigging hot in Florida. Trust me, my family lives there and I practically grew up in the Orlando area every summer when I was younger. Kids get hot, it's crowded, they're cranky. If you stay on property, you get free transportation (trust me, a nice, cold air conditioned bus taking you where you need to go is a lifesaver when you're sweating so much you can't tell when you started weeping!) and you can take a MUCH NEEDED break mid-day, when the kids are cranky, to either give them a quickie nap in the nice, cool (sensing a theme here?) air conditioned room, or you can all go to the pools to cool off and play (again, talking to other people I've heard that the kids love it and don't feel they're missing out on anything), or you can go to a water park for two hours to cool off and then go back to the parks (and you don't have to drive anywhere if you take the Disney transportation). You can wake the kids up early, have breakfast, go to a park, come back for two or three hours, then head back when it's afternoon, cooling down, and catch all the fireworks, etc. The parks chill a bit, crowd-wise, in the afternoons. There are certain days that certain parks are more crowded- you'll read this in your guide book and it's SO true. I just noticed you're going in February- that's good...the parks are much less crowded, and the weather is better.
My tips off the top of my head:
-Do the package deal at MGM where you buy dinner (one entree needed, I believe) at one of the participating restaraunts (one is a buffet, I believe, with character visits) and then get special tickets at the end of your meal to take a back entrance to the MGM Fantasmic fireworks show. IT'S AMAZING, the kids will LOVE it, and it made me cry my eyeballs out. SO worth it, and you get a nice dinner out of the deal. You get to pick the restaurant- we're childless, so the first year we ate at Mama Melrose's (Italian) and the second year at the Brown Derby (ohlala, I love that place!). You get to go in the back way to a special seating area for the show, instead of having to show up two hours early to try to get a seat. DO THIS. I never regretted it, and you won't find this advertised at the park. You have to know about it ahead of time, and when you get to the hotel you can make reservations.
-Do the Fast Pass thing- this will save you so much time and effort you won't be able to believe it. First thing in the park, get your first FP right away. You go at the designated time (usually 1-2 hours from the time you get your pass at the ticket machine) and get to walk right into the ride without waiting. Well, you waited the 1-2 hours, but you don't have to wait in line. You can go ride another ride, eat, whatever, then just walk back to the ride and get right on. Very nice. We rode Tower of Terror five times in one day like this (we're freaks, I know...) and never ever had to wait more than five minutes before getting on the ride.
-Join the Disney club (or whatever it's called now...I think they changed the name). For about $50 bucks you get SERIOUS discounts on the hotels, ticket packages, dinners at select restaurants, freebies for the kids, etc. Worth it- pays for itself if you use the hotel discounts alone. You might be able to get this card through your work at a discounted price. If you get it now, they'll start sending you hotel discounts and coupons right away, so you'll be able to use them in February. You can also purchase this at the Disney stores, I think.
I just priced it on the WDW site, and for example, if you arrived on Mon. Dec 1 and stayed at one of the All-Star resorts, your room would be 109$/night. Don't know if that's within your budget, but if it is, I highly suggest that you consider it. IT'S SO WORTH IT. I believe that on certain days some of the characters visit the resorts on a bus and the kids can go meet them, you get all the perks, free transportation (did I mention this is a LIFESAVER?), etc. You are eligible to do the E-Ride nights, if they have them in February (where you go to the parks when they've closed and get to ride the rides without the lines, etc. I think it's like 10 bucks a ticket and only available to resort guests).
Okay, I've gone on enough. I have to go price my imaginary trip to Disney now.
