it is 10 years since I went to Burnham on Sea and it had was wonderful then. We had several holidays there and loved every one of them. Obviously over the years the staff will have changed but there were two lovely pools and good entertainment. (IF Dave Jade is performing you just have to see him)
Burnham is a lovely little place with a great ice cream parlour and nice shops. Neaby is Brean Sands with a fun fair. I don't know how old your kiddies are but we went there when mine were from eight till they were about 14 and they just loved every holiday we had there. I do hope it is still as good and that you enjoy it.
