Good news for those of us who love ball parks but arnt allowed in any more. There is a place in Portsmouth called Playzone that has over 18's nights on the first friday of every month. I went last night and it was awesome fun. It reminded me of Fun House, lots of squishy rollers to squeeze through and things to climb. Everything is padded and everyone is running around playing tag and generally enjoying being a kid again.
Only downside was some chavs in there and the rubbish music but its well worth a visit if you get the chance. Oh and did I mention the HUGE slide My friends found out about it, They were loving it as much as I was. Guess theres some kid in all of us
You could always combine a visit with SIDF too!
