I will be in the UK for 3 weeks in Sept. First 4 days, London, then a, 8 day cruise, then a roughly 10 day driving tour of southern UK (Cornwall/Devon/Cotswalds). We already have 3 day London GO cards, Overseas Visitor Heritage passes, Buckingham, and Highclere passes.
Just found out about the Taste of UK card https://www.tastecard.co.uk/ . Looks like it would cost me £1 for the duration of my trip and give 50% off or 2for1 on many London restaurants. Has anyone used that card? Seems like a pretty diverse list of restaurants and not just fast food/chains.
Any other discount cards out there that anyone suggests?
