Hi Dave,
My wife and I stayed there 2 years ago with our then 1 year old. Great site, nice level pitches. Couple of points to be aware of, The entry road in to the site is very narrow (we met 2 caravans coming out as we were arriving). It may be worth parking up on the main road and sending your other half on ahead if you are arriving at a busy time. Also we felt that the shower block was'nt up to much, but this may have been refurbished since our visit. If you have a young family it is worth standing your ground at reception for a key to the parent and child room, they seem very reluctant to give these out as it is also the disabled facilities.
Don't be put off, we had a great holiday here. So much to see on IOW.
Cheers
Dave
