I live in the UK so generally the view is Florida is a beautiful place where the rain barely falls, yet a few years ago I heard that Florida is actually not a great place to live, pretty dirty and one of the rainiest places to live in the USA, just wondering how true this is.
I also heard that Disney land Florida is pretty dirty, somewhat of a let down? Is there any truth to it?
Disney "World" is really nice (Disney Land is in California). It is actually amazing how clean they keep a park that size and they do most of it without you noticing it much. You certainly don't see any garbage laying on the ground, ever.
As for a letdown, it depends on what you are looking forward in doing and not having ridiculous expectations. *See Paris Syndrome.
For a first visitor you will be overwhelmed with the scale of things. The first time we went to Disney we tried to do EVERYTHING and we exhausted ourselves (literally). I would make a plan on things you really want to do, ride, characters to pictures with, shows to see, parades, fireworks, etc. Start from there and whatever extra you do is a bonus. You can get a free dvd and maps from some Disney websites that will help. I recommend
www.mousesavers.com as it helped me out greatly. Plus the time of the year will factor majorly on how much you will enjoy going. I have been to Disney World four times in different times of the year. (December (Busiest time), Jan/Feb, June/July, Aug/Sept.) Certain times of the year are busier (you can find that on Mouse Savers) such as Christmas break, March Break, Thanksgiving, etc. Anytime people have time off from Holidays expect it to be busy. However if you have flexibility you can book in between these holidays and have far less of a crowd to deal with (less people=shorter lines and more time to enjoy everything without waiting). Weather can also be a downer as when we went in June/July and Aug/Sept it was ridiculously hot and humid (Imagine turning your oven on and sticking your head in) There were days where you wouldn't get a lick of wind or rain. Trust me you welcome a little bit of rain, which comes in passing showers (more during the winter months). Of course if you plan accordingly you can be inside the nice air conditioned rides during the hottest parts of the day. FYI - June/July not a good time to go as a lot of tourist/students from Central/South America visit during this time and make the parks busy. As for Aug/Sept this was probably the emptiest I have seen the parks EVER. But be warned this is Hurricane season down there but I don't believe a hurricane has ever reached that far inland as Disney World. The first time I went to Disney we were hit by a tropical storm which just resulted in a bit of rain and wind (which was nice due to all the heat we had). My sister actually called and was worried but at that point I didn't even know we were being hit by a storm.
There are four major Parks (Magic Kingdom, Animal Kingdom, Epcot, and Hollywood Studios), two water parks, and then there are things like Disney Quest. I would plan at least 2 days for Magic Kingdom, one day each for Epcot and Animal, and you get away with half a day to a day at Hollywood Studios but pick a day they do the Fantasia show. You could certainly spend more time if you want at these parks but I am just giving you a heads up on how much to at least spend in each park
If you can afford it and have the time I would also try to visit Universal Studios. The roller coasters are far better, there is Marvel Super Hero Island and two words... Harry Potter. We spent two days with hopper passes to visit both parks each day and we got to ride every ride at both parks multiple times and some like the Hulk coaster and Dragon's Challenge several times.
