Thanks for all the advice

do you know when the dates of those events will be released? I would love to do the Halloween one. Luckily for this trip money is not too much of a worry and we happy to spend a bit more of we have to as we have waited so long for this trip and have the luxury of a more flexible budget. I think I'll definitely have to find out a bit more about port Orleans as it sounds great! Do you know if you can already book for September/October hotel reservations? I definitely want to do BBB as DD7 is still into dressing up and loves the disney princesses and I don't know how much longer that will last so definitely want to do that while she's still into it and I'm sure DD3 will love it too! I definitely think I might buy a few glow sticks and light up toys from the dollar stores before going though because I hate wasting money on junk that I know they won't use again! I love the sound of those kidcot stops in Epcot I think the kids will love that!
Thanks for the advice about the change of clothes & medicines will definitely do both!
I'm still unsure about what to do about the stroller, as DD1 will need one, but don't know about DD3 & DS3 - although they will be 4 when we go.
Thanks for all the great advice
