as someone born and bred and still living in Hastings would suggest the following:
Sea Life centre (Hastings Old Town). Well worth a visit.
Smugglers adventure - The Caves - West Hill Hastings. Good fun
Both East and West Hill Cliff railways if they are running.
Alexandra park - has playground for the kids.
Hastings Country park - area of outstanding Scientific Interest - lovely walks and rambles through Ecclesbourne Glen and Fairlight Glen and along the Cliffs.
Fishing Quarter - Hastings Old Town - nice old boats and good fresh fish/crab/lobster etc.
Hastings seafront has the standard 'fun-fair' attractions if you like that sort of thing? Dunkin Do-nuts are a must
For really good Fish and Chips - The Blue Dolphin (end of High Street in the Old Town) eat in or take away but be prepared to queue
For Ice Creams - Doms Ice cream - Best in Hastings.
Avoid Central St leonards - full of unpleasant people and nothing to see anyway.

Oh yes - meant to say - if you want to pop in for a cuppa drop me a line
