God man, you've been flat out by the sounds of it, but it does sound like a lot of fun.
I've been in a simular situation, I was in Blackpool last week, then this week had a friend down for a few days staying for my birthday and then next week my cousins going away party is on plus a few other things; it's been a lot of fun, but I can't wait for a bit of quiet time when it's all over.
The forest walk looked like some fun, and you're right man, the best things in life are certainly free.
