Hi Liz
You're never on your own during a JY holiday unless you chose to be. One of the many roles of the rep is to ensure that no one gets left out.. Generally it is easy to find other people who want to do what you want to on the leisure days and the rep facilitates that if necessary.
I can't recommend these holidays enough - I've been doing them for ten years now and have loved every single trip. You are with a group of like-minded people, in beautiful surroundings, having an amazing holiday. You will never laugh so much and as soon as you get home you'll find yourself thumbing through the brochure for your next trip.
Once you take the leap I promise you will wish you'd done it sooner.
