Will be arriving LHR on 4/30 and pick up car next day heading out to Port Isaac for 2 nights, will be visiting St. Ives and Penzance, St. Michael's Mt. Have 3 more nights before heading back to London. Since 5/2 is UK's public holiday (Bank Day) I am worry about heavy traffic. On our return to LHR to drop off car I like to know where we should stop and visit along the way. Have been to Bath and Oxford. Should we venture over to Wales a bit and spend a night or 2 before heading East? Any suggestions - where to stay and good restaurants would be greatly appreciated.
