Thanks Hank!
That's good to know about shopping in Sorrento, which of course does determine whether I go to Sorrento before Pompeii.
I was thinking of doing Capri, but was reading that it costs 17 euro (?) each way. And for a group of 5, that comes out to 170 euro, which is 240 dollars about....so not sure I really want to spend that much just getting there and back...would prefer to stretch my dollar. I also read the blue grotto is about 10 euro each, so that would be another 50 euro...
