So - coppi, BQ and Vello - I've looked at the options for the weekend of the 6/7 August and, despite claims to the contrary, there doesn't seem to be much difference in price between the ferry or eurotunnel (unless one of you can get more sense out of the eurotunnel website than I can). It's gonna come in at around £70 return.
If we do the ferry from Portsmouth to Le Havre, we can do the overnight sailing than leaves at 23.00, sleep on the boat and get there early morning for a full day's ride on the Saturday and come back on the 17.00 on the Sunday for a late arrival back in London.
This gives us a good amount of time in France, and only need to find a hotel for one night. We also get to nice roads (IMO) quicker, say towards Saint Malo - and have the bonus of a ride over Le Pont de Normandie at Honfleur, in and out of Le Havre - le pont de normandie - Google Search
Happy to go with eurotunnel, if one of you can get a better deal. Either way, we should probably book by this weekend, so let me know what you fancy. M
So anyway, yeah, all this sounds fine to me.
