My in-laws are treating the family to a big holiday in a couple of years and we are currently trying to decide where to go. They have put aside quite a lot of money as want it to be a special, once in a lifetime experience. There will be 8 adults and 7 children ranging from between 3 years and 10 years. One of the children is very sensitive to sunlight so they can't go anywhere too hot and one has quite a few food allergies so wants to be somewhere where they can get fairly familiar food. Suggestions so far have been Canada, somewhere in Scandinavia and New England. Where would you recommend? In terms of country and also any actual accommodation you've been to which you would recommend?
