It's my local site but I can't say that I'm a big fan of it. Too many hills and rhododendron bushes for my liking. Knackers my legs and you find some bugger camping in a bush locking a path down and it's damn near impossible to see them.
It's good for beginners and kids, staff are friendly enough and facilities are good, the shooting range is a two-storey wild west saloon, which is quite cool. There are some interesting area on the site (i.e. The fort and village etc.)
I find the Sunday game play a bit boring - it's a single game that lasts all day with objectives that have to be hit at set times throughout. You spend ages moving from objective to objective (the site is massive) but on quieter days you can go for quite some time without seeing the enemy team. Even if you do, the firefights a bit pointless unless you are on top of an objective.
Saturday games are better - individual attack/defend games at certain (smaller) locations throughout the site.
It's probably a good place to start back, but I would be looking slightly further afield in future, there some great sites within an hour or so drive of Bournemouth (e.g. UCAP Bunker/Dorchester Prison, Ironsight in Andover etc)
Have fun.
