Planning an overnight trip to Manchester for ds1’s birthday (16) as he wants to go round the football museum. Dd is going on a trip with school, so don’t need to worry about her getting bored. . Ds2 will be with us, he’s 8. Just wondering what else is worth doing on the same day? I’ve looked online and seems there’s a few museums, but none stand out really. Both like footy (but support Arsenal, so etihad / old Trafford of no interest). Would like natural history museum type place. Or any outdoor spaces of interest? TIA for any suggestions.
