Hello Patti
I am one of the Tour Managers with JY and I did this trip last year and hopefully I'll be taking it again in May and June this year. It's a lovely weekend and Monet's Garden is beautiful, especially if we're lucky enough to have some sunshine!
I often find I have a number of first time JY travellers on the short breaks as it is a great introduction. As for courage, I can assure you you will meet some really friendly people.
Hopefully I'll see you at the Eurostar check in in May.
All the best, Lynne
