You will have a great time..As an expert in the attractions (wife) we have had yearly passes to all the parks on a rotating basis..This year was Universal, last year Sea World, and the year before that Disney..My kids are 6 and 8. Their favorite was Sea World then Universal and finally Disney. I personally hate Disney for the simple reason that it is so freakin crowded. 95 degree heat and a packed park does not make a pleasant time for mom and dad. If you do go to any park I highly HIGHLY suggest get there and be at the doors when the park opens. Go to the most popular rides and attractions first. You will be amazed what you can accomplish from 9am -10am..Once 12 noon rolls around you will see massive crowds moving in. Once you have done the big atrractions you can always decide to leave..You also have to consider afternoon rain so GET YOUR ASS UP EARLY. Don't know how young your littlest one is but height to ride most coasters was 48 and 42". My 8yr daughter loved the coasters at Universal. That is my favorite place by far..
As far as food my favorite place in the area is Taverna Opa if you like greek food. Belly dancers on the tables..kids loved it and so did Dad..Enjoy the trip
