Hi so we are looking at booking Orlando/disney/universal for a dream holiday for me my husband and three children aged 13, 12 & 10. All the reviews have said the heat is almost unbearable, but we are limited to july because of school holidays & work commitments. we usually holiday in France/Spain and the kids manage fine with the heat. I'd just like some reassurance really! we are staying onsite in disney and universal so I was thinking we can go out to the parks early then head back to the pool for the afternoon then out again in the eve?
