Will be traveling with my 18 year old daughter and was planning on spending four nights in Positano and then four nights in Capri. I'm now wondering if it makes sense to spend one of those nights in Ischia instead of just doing a day trip there from Capri? It would certainly be a bit more effort to relocate one more time during such a short trip, but wondering if it may be worth it?? I know very little about Ischia and whether the overnight would make it in fact a very special last day. IF you think so, what area would you recommend that would have a lovely beach and close acccess to shops, restaurants. etc?
