Capri is beautiful, but there isn't much to do but shop, when they take you to Anacapri (upper island). If offered the Grotto excursion, take it first, then goto Anacapri. The tour guides were knowledgable and nice to chat with when not guiding the tour. It would have been nice to have had a chance to see more of the island, maybe take a boat out around the coast, then do a shopping and dining trip to the top of the island. So, ask about the Grotto excursion too. After the trip, they drop you back at your hotel, but make sure that they have the correct address. They missed my hotel by 3 blocks. Fortunately, I knew my way around well enough to realize their mistake, so I was able to find my hotel after they left.
