We stayed at Sunset Beach a few years ago, and it is excellent for families. There are various pools, including one situated right next to the restaurant, they had two bbq evenings in the week we were there, with the kids running around, and playing on bikes, scooters etc. The beach is shingle but as Jacqui says cheap beach shoes are available in the local shops, and it really is only a short flat walk back to the prom. There is a brilliant on-site massage and Turkish bath, which is very good value, also an indoor pool if you want a break from children. The staff were excellent, very friendly and helpful, and we booked two trips through reception, and were picked up from the front of the complex. Although as a single person I would not go there again, I could thoroughly recommend it for a young family, ground floor would be best with small children.
