I know I will be visiting BPB and Thorpe but aside from that it depends on other commitments and where we go on holidays etc...
Blackpool Pleasure Beach (but probably not as many visits as last year unless operations have improved), Thorpe, Oakwood, Lightwater Valley, Flamingo Land, Drayton (probably), Alton (if anything's open), Paultons (probably), PWH and GYPB (maybe), Brean (maybe).
Probably a visit to Chessington during main season as well to remind myself why I only visit once a year.
I would like to visit Adventure Island at some point as well as Dreamland, but unlikely to be this year.
