We had our first family camping trip over the bank holiday and it was FANTASTIC! So, we're planning more over the summer. We've got a cool bag but its pretty hopeless so am planning to buy a new one and was wondering if it was worth getting an electric one or just getting a big solid one and more ice blocks. Gadgetboy DP is convinced only an electric one will do but I was wondering if they were really worth the extra? (especially as I am now lusting after lots of other camping bits)
