Tam77 - i've just returned from Orlando with my 6 month old and we're going again the end of April. If you're there for easter it will be busy because its a major holiday in America, not just in Disney but everywhere. We were really surprised at how many of the disney rides at all the parks we could go on, esp with a 6 month old.
You can't buy single day passes in the Uk but you can when you get there.
A single entrance ticket for your son will be $56 and for you $67 they're available at the parks ticket offices. You may drive past ticket booths outside of Disney offering cheap passes, although some are genuine we have never risked them, the sellers cannot prove how long is left on the pass, you could be paying for an expire pass.
Other parks that he might like are seaworld and universal studios, the main park has a nickelodeon section which the younger kids love.
There are certain rules when driving in Florida that are differen to here. we went with Virgin and they sent us a guide to driving and getting around Orlando, if you would like me to post it to you, then please email me at [email protected]. The americans aren't particularly polite drivers and don't appear to take into account that there are lots of tourists on there roads. just go steady and stay calm, thats the biggest tip, and keep your eye on the signs all the time.
For info on hotels, visit www.tripadvisor.com, they will have reviews written by guests. I've read them for your hotel, and there are some good and bad points as with all places. might be worth you knowing about them though before you get there.
The weather is changeable, one minute its hot then its cold and raining. in December 2006 it was 80 degrees.
if you visit this link disneyuksite at the bottom it shows you the current weather.
if you visit usa site you will be able to choose tickets and see prices on one of the pages, pretend you're an american resident, or it will send you to the uk site. you can also see what there is for all the age groups of children.
hoep this helps, anything else i can do email me.
