Blimey - one of the advantages of one boat cruises I suppose - just get on with it make you own choices
I am extremely sceptical about managing to get all these things to occur at the same time in that one week window :-
1) a weather window (which will now have to be 2 days long which is twice as unlikely)
2) baby sitters that can have the kids for 2 days including a night stop over.
3) accommodation for all for one single night but we cant tell them what night it is going to be until a couple of days before we come.
4) My other 2 crew being available.
It'll end up me not going on my own cruise because of baby sitters or my mates not being available.
I just been to Fowey and back this Saturday - which is only about 5 miles less in distance but we hugged the coast and stopped at various places so probably total miles was the same as we did not go in a straight line. We didn't even leave Mylor till 11:00am had a very leisurely lunch and were back on the slip at 3:30pm. If the sea is so rough we cant even maintain 15 knots im not going anyway.
I'm all for having a stopover as an emergency backup but I reckon if we plan for 2 days it wont end up happening.
