Holiday

I am currently saving money to take a holiday hopefully next year with my little princess. She wants to go to disneyland and also the beach. I personally would prefer to go somewhere with a beach than disneyland, plus its very expensive to go there. Any thoughts on a good place for a single mum? which would enable us both to have a good time. I want to avoid hotels which are full of people drinking alcohol all day. But if anyone knows of any good hotels, or area? which are affordable I would love to hear from you! Thankyou.
