So there was a thread on Mumsnet earlier (sorry I can't remember who started it and I can't find it now...) about someone who was wanting to avoid their MIL and so was going to tell her she was travelling the country for the whole of the summer visiting Mumsnetters.
Next summer is ds1's last before he starts secondary school, so I had a lightbulb moment and am thinking dp, me and ds's (will be 11 and 9) could take a month to travel round the country! 
We'd do it via train as dp and ds1 don't like being in the car. I'm thinking trains + youth hostels, rucksack each! Dp's been sent off to buy a map of the British Isles which we can pin up and start marking places we'd like to visit.
So far, ds's have mentioned London, Blackpool and Liverpool
. It's a start..! I'd like to include Scotland and Ireland - never been to Ireland before.
What do you think - too bonkers to consider..? Has anyone done this in the past and any advice on train travel - is there a family annual UK-wide pass type of thing at all? We've got a friends and family card but I don't know about anything else.
Anyway, just thought I'd share my giddiness dp thinks I'm completely bonkers. Need to start saving and planning...
