Hi Jamie - try this site: http://www.weatherunderground.com/h...=Kissimmee&req_state=FL&req_statename=Florida
It's called weather underground and has a trip planner section which shows the average highs and lows over recent years so you can get an idea.
I've set it up for Florida so you should just have to put in the dates you wanted.
Hope it helps
RJ
Should be ok - they are more susceptible to cold snaps in December - but even if you get unlucky, the weather is still in the late 50's - 60's, and it is usually only for a couple of days until it warms back up to the mid 70's.
The noticeably colder times are early morning and late evening - you will almost certainly need trousers and long sleeves at those times. Otherwise, hopefully the sun will be shining .
pack for both hot and cold...
we've been there in december when it was in the 80's the entire time..
and we've been there when we had to wear winter parkas, wool hats and gloves...
I'm there in December from the 15th until the 29th and I'm hoping for a mini heatwave
I've read quite a few threads and weather sites, and it seems the weather can be very unpredictable. Hot one day and quite cold the next.
Looking at yearly records the rain fall is quite small though (compared to summer!).
SNAP we fly out on the 14th Dec and come back on the 28th, i have been advised to pack for all kinds of weather, but i'm planning not to pack too much as my kids need kitting out so i thought it would be a good excuse to do some SHOPPING
Even if the days are warm the evenings do get very cold particularly if you are standing around waiting for parades, waiting for Fantasmic to start etc. The mornings can be chilly too.
