Sounds lovely. Kids under three are free, adults £5, older kids £3.50. Big butterfly house with hundreds of exotic species, a maze, a slide, etc. Anyway sounds a nice day out and of course a nice cafe lunch. My ds is 2.5 and I'd like to go sometime in the next two weeks. Any weekday except Tue is OK for me. Anyone else fancy it with their little ones.
