In reply to becdent:
There are two bank holiday weekends back to back, so it may be worth your while to leave on thursday night and return on mayday monday.
It will be very busy, due to the above, but the atmosphere is amazing, we have been for the last two years, the first year the weather was lovely, easter fell in the middle of april and we had a great time, last year was not so good as easter fell at the end of march and it mainly rained! Due to the lateness of easter this year, I'm hoping for good weather.
There is a group of 12 of us heading down this year, so it should be great.
