My husband, teenage son and I will be in Cornwall (St. Austell) for a week in July. We will be hiring a car but are unsure about the roads. How busy will they be in July? Are there numerous one-way systems in operation? Is there good signposting? Based on other reviews, I'm thinking twice about driving to Land's End and we're even debating whether to visit the Eden Project due to the possible huge crowds. However, we really want to go to the Scilly Isles - any advice or information would be most appreciated.
