Hi Hilary,
Just seen your message. This will be my 4th Just You holiday in less than 2 years! Just got back from Americas Parks & Canyons 5 weeks ago (best holiday ever!) and I booked this 5 days later! On all the holidays everyone got on really well and the age range on the last one was 26 to 83! so no worries about that!
Book it - you'll be well looked after!
Regards,
Pat
