The Orchards Isle of Wight Directions etc?

Hi

We are off to the Orchards site on the IOW next week and I have a few questions that I am sue someone on here will be able to answer. I have studied the directions given in the club site book and they seem pretty straightforward but I was wondering if anyone could give more detailed directions e.g where to go when leaving the terminal at Fishbourne. We are travelling from Portsmouth to Fishbourne on the wightlink ferry I am not concerned about taking the van onto the ferry as I have done it a few times before when we have gone to France and have never had a problem but I was wonderig if anyone who has been on this particular route could give any advice e.g is it fairly straightforward to get on and off the ferry is it "roll on roll off" etc. Any advice and opinions would be much appreciated.

Many Thanks!
