Hi Bill
I tried my first JY 2 years ago, and Malta will be my 4th holiday. I've never looked back. You usually get quite a mixed crowd, but everyone is very friendly - and just remember that everyone is doing the same as you - travelling/having a holiday on their own.
The first time is a bit scary, but after that you realise there's nothing to be scared about!
So I say, take the plunge, you won't regret it.
