Family Friendly Meeting Spot - A64 to A1/M18 junction

[ellemmjay]

Please help

I'm trying to meet up with friends tomorrow mornin

Between us we have 3 toddlers - 3 1/2 ; 2 1/2 and 9 mths

Any suggestions for places off the a1 BETWEEN THE a64 junction and the A1/M18 junction

Many thanks

Is York too far off the A1? If not then easy enough - Railway Museum! Easy to find, you can park easily, very pushchair friendly, toddlers love it and it's good fun for adults too!
The gardens and tearoom at Brodsworth Hall will be open it's off the A1, near Doncaster, off at junction 37 - but if the westher is dodgy I don't think you'd find enough to do.
Bit stuck otherwise....
