I have a monthly one for £20.99 which started Aug last year. I took a year off from parks the year prior and before that I had a Merlin pass since 2013 - started with Merlin Membership standard pass then they phased out the pay monthly ones so I moved to Platinum. The year before I took a break I had a Gold annual pass which never scanned and was a pain at Thorpes turnstiles. I now have platinum pay monthly and when I’m out of my contract I will either move to a Gold monthly pass or take some more time off.
Back in 2002/2003 I had a Tussauds off peak 2 park pass for Chessie and Thorpe on off peak days - cost £35 and got a lot of use out of it.
I live in Surrey so am only about 25 miles from Thorpe, Lego and Chessie but don’t actually visit a huge amount currently
