Did You know there are HUGE DISCOUNTS this year at Most Theme Parks..
Including Disney !
Disneyland Paris especially have big discounts for UK customers.
This is of course due to the recession but it might be worth a day trip on the ferry if the deal looks good enough.

As far as I can gather the deal includes park admission,discount hotels and free entrance for kids.
The deals in the USA however mostly seem to be for state residents of Florida and California.
