Hello Angel-49
I've been to both Sicily and Malta but not this holiday as it's new. Both countries are wonderful with good weather and lots of history. If I hadn't been to both islands I would certainly be tempted with this as I've always wanted to island hop.
As regards plucking up courage, if this is a place you've always wanted to visit just go for it. My first holiday with JY was in March 2010 to New Zealand and I've been booking ever since! You will have fun and wonder why you worried and will become hooked like the rest of us.
Happy Holidays
Sylvia
