hiya Mary.... I'll be at Whitby so will look out for you...don't buy a ticket at least until you see the programme and know what you want to see & do..there's lots going on for free ...
If you want to see official stuff it's often cheaper to pay on the door...although the concerts might be £10 or so workshops are only about £3...you could do a week of accordian workshops for £15 a season ticket would cost £100 with an extra £24 to camp... you can get camping only tickets for £30 for adults ....I assume that's per head not per unit... so still would be £60... Stakesby School isn't available this year so camping space will be at a premium...
I think I'd be inclined to go for Stoop cross and commute by taxi... if your knee can manage steps you'll be OK coming in.
You'll usually find catter's in theTap & Spile..see you there!
