There is one by the marina-its a sea scout site that rents out CC or C&CCor there is also one behind pleasureland but only has water and toilet dump (£8 per night-gated)-both are close to the seafront and 5 mins from town
It's in the c&cc book under Waterside Lodge. It's about £18.00 per night, on the sea front. Tel 01704 910900. You need to ring during the day, as the office is closed at night. Quite nice, overlooks the sailing lake.
