Hi Vanessa, welcome to solo holidays, you've chosen a good company to travel with, I've had many holidays with JY and enjoyed every one.
Croatia is lovely, I've done 2 of the JY trips there, which are you doing?
It's natural to be nervous but there's really nothing to worry about, you'll be fine and well looked after. One tip I'd give you is to put one of your luggage labels on your hand luggage so that other JY travellers can spot you at the airport, also look out for anyone with a label on theirs and go and say hello.
Happy travels
Rose
