We spend the day yesterday at The Crane. They have an unadvertised deal where you can spend the day at The Crane for $25 BBD ($12.50 US). You get access to the beach and the money you spend can be used as a credit at their restaurants. We also checked out the pools.
The beach at The Crane (Crane beach) is pretty nice though the surf can be a little harsh (though fun to play in). The grounds are also very nice. While the pools look really nice, I have to say they are disappointing as they are too shallow. While they say four feet, they are really three feet, (unless I've been 8 feet tall).
We had lunch at the Azure restaurant overlooking the beach.
Since your entry fee gives you equal credit at the restaurants, you can view it as almost a free day and as such I have to recommend it.
We can in from Hastings so the bus ride was about 40 minutes exactly. The bus stops right in front of the Crane.
