I don't know yet if our plans allow a stopover in the UK, but maybe some of the British members can be persuaded to cross the Canal for the occasion? If Alex B. is still on for his Rotterdam trip 1/2 July, we could perhaps arrange something around that.
Ryanair flights are dead cheap, and they fly twice a day, including an evening flight, which is perhaps the most safe option for Derek.
Any volunteers?
(BTW, we also plan to go to Porto/Douro that period, so an offline there is also very well possible.
