Yes, maybe that is a bit tight
. Honfleur is lovely, but I've been a number of times before and stayed overnight too. So the thought of paying an extra £50 for a quick walk round the harbour and a visit to a chocolate shop seemed unappealing.
[Edited to add...]
I'll be flying from Cranfield and should be able to take at least one other. I'll probably fly IFR in the airways, so it may be a good opportunity for someone who's thinking about doing an IR and wants to see what you get for your money.
Dates are difficult for me. I can definitely do either the 14th/15th July or the 25th/26th August, but anything in between is unlikely.
