We had the opportunity to sail on the Discoverer in September on the Lost Islands of Micronesia and Melanesia, voyage 9520. The actual itinerary underwent some changes from when it was originally printed (I think that's what is showing here) and what actually was sailed. And then we had further changes due to weather while we were cruising! Rule #1 of expeditions, expect the itinerary to change. If you understand this ahead of time, you will be okay and will have a fabulous time. The ship itself was well built for what we were cruising for (smaller ship, smaller less visited ports). Everything is off-the-beaten path. We LOVED the expedition staff, their interaction throughout the day with guests, and their presentations shared during the cruise. They are each consummate professionals. Having a butler for our stateroom was a first for us; we liked it, but don't find it something we have to have for every cruise. Overall, it whet our appetite to try Silversea's classic fleet such as the Cloud, Muse, etc. We plan on cruising the Expedition fleet for the Arctic and Antarctic for sure.
