I realise that this is a bit of a pointless thread, but as it's not a proper review, and I really just wanted to come back and thank all you lovely posters for all the great advice, I couldn't not post. So, here goes...
Not only did we survive our first camping trip, dh, myself and our 17-month old son absolutely loved it! The weather was brilliant, the tent stayed up (go figure!), and I eventually got my fire started.
We went to Blackberry Wood, which is beautiful and just what we needed for a first "try".
Riven and Slubber, if you're reading this - thanks for the tent suggestion. Vango Orchy 500 great for us.
Sorry, I'm just so stupidly excited. Will shut up now. Wish it was beginning of summer already...
