I'm planning a holiday to celebrate PIL 60th birthdays in 2011 (I know I know!)
3 generations, the grandchildren will be between a few months to 5 years old.
SIL and family live in Wisconsin and we'll be coming from the UK.
The obvious choice is Florida I suppose but think the children will be too young for disney. Any suggestions for destinations relatively easy to get to from the UK, reasonable weather (but not too hot) and plenty for preschoolers to be entertained by.
