Try Thornwick bay the cost is £180 for a chalet ( or shed as I like to call it ) or a caravan is about £280 both include all electric there is a surcharge of I think £20 per person to sail in the evenings in the pool and use of the hall for indoor flying in the daytime you can also contact me for a weeks membership to Bridlington Model Boat Society ( £5) this will give you a weeks unlimited use of the lake as long as you abide by the club rules which are supplied with the weeks pass.
There is also another week in September/october which s £140 for a week you must say you are booking for the modellers week to get the above prices , as of last thursday there were very few chalets left for the spring.
Any other info P.M. me
Cheers
Bob
