We would like to go away for 1-2 weeks at the beginning of September. DD will be nearly 4 and we will be taking advantage of the last September before she goes to school. We'd like to go somewhere abroad as she would like to go in a plane, but we aren't willing to fly Ryanair. We normally holiday in the UK and get a cottage. We aren't great with heat, so are looking for low 20s rather than high temperatures. We aren't really people to laze about by the pool - we'd like somewhere with interesting places for day excursions that would be reasonably interesting for a 3/4 year old. She does like beaches and paddling in the sea.
Please could you suggest something that might fit the bill.
