As for the things to do in Orlando, the list is endless. For older children and adults, Universal Studios is usually the most popular. There are lots of thrill rides there and the rides are based on films they will have seen such as ET, Terminator, Spiderman, The Hulk, The Mummy, Back to the Future, Jaws etc.
Universal is split into 2 parks and you can get special tickets to cover it plus other parks. This is called a Flexi ticket. best domains Latvia It allows 14 days access from day of first use to: Universal Studios, Islands of Adventure, Sea World and Wet and Wild Water Park).
You should also visit Universal in the evening as the City Walk, is full of restaurants, bars with live music and shops, and is great fun to walk around in the warm evenings. If you are visiting in October, Universal does the best Halloween Fright Night I have ever seen. It is worth travelling in October just to go to this.
Disney has 4 main parks, which are Magic Kingdom, Epcot Centre, MGM Studios and Animal Kingdom. The best option for Disney is definitely the ticket that allows you to hop from park to park on the same day and gives you entrance to one of the water parks which are excellent.
The Water Parks are called Blizzard Beach and Typhoon lagoon. My kids tended to like Typhoon Lagoon the best because of the wave machine but this may be a bit powerful for smaller children and non- swimmers.
Disney tickets are cheaper for kids, but they have to be under 10 yrs, and most younger children like The Magic Kingdom the best as they get to see the great day and evening parades with all their favourite disney characters. The evening Light Parade is also very popular, but make sure that it is on on the day you go.
