Hi Susanjane, I have just booked the Mykonos & Santorini for the 20th May.
It is my first time with JY too and also nervous, yes I do understand how you are feeling lets hope we'd made the right decisions. I am not sure if I will be staying in the hotel on the 19th, if I do I will let you know then we can meet up for a drink.

Cheers!!
