The last true "family vacation" I can remember going on... was one of those phatty Florida Holidays. My mom, Colin, Canela & I flew down to Florida, and enjoyed almost every aspect of the place/s that we could!
Obviously, we hit Disney World & Epcot all the way. We got one of those 5-7 day Flex Passes, and alternated between the Magic Kingdom (same thing as DisneyLand; just more stretched out & with more shops,) Epcot (hitting all the countries we could, eating there as well!,) Disney/MGM Studios (a slightly different expreience than that of your typical Universal Studios,) & the outlying Water Park for a bit of a break. Disney was great, almost too much to take in so quickly, but we hardly made a dent there!
Aside from the vast Disney experience, we flew further down state, rented a car, and drove out to the keys. My mother had discovered the Dolphin Research Center, and arranged for us to swim with the dolphins! It was quite the drive, but worth it! Plus we got some really good cuban food along the way, yum!
