is there a best day to go that's less busy?
Don't think it really matters as they only allow 100 guests a day I thought. I'm pretty sure it was at or very near capacity when we went in october and it didn;t seem busy at all - there was no wait for breakfast or lunch and you could get a sunlounger anywhere. The only time there was a bit of a queue anywhere was for the photographs at the end of the day and even that wasn't bad.
We were there when it was at full capacity in July, but it never felt busy or crowded. I think thatís why itís such a lovely day. The place feels a million miles away from the hustle and bustle of the other parks.
