Looking ahead to next year, it will be the last time we can have a long - 3 weeks or so - holiday outside of the school holidays, so thought we'd make it a good'un.
DD will be just over 4, DS will be 21 months. Thinking of going in June, happy to fly a fair distance as the length of holiday will allow us to forget about the horrendous journey there!! 
Usual holidays for us are getting a cottage in Cornwall - beaches and paddling predominate. Train rides, animals, running around are all popular with DD, DS currently too young to care!
So have any of you done any fantastic holidays with similar aged children that you can recommend? Or any you can advise against?
I had thought of Disney, DS will clearly be too young to get much out of it, will DD too? Was thinking this would probably be worth the money when they're both quite a bit older? We went to South Africa when DD was 19 months, that was great, but it will be winter in June....
Thanks for any tips and advice! :)
