We loved everything about this cruise except for the wifi. So let me get that out of the way first. Oceania, you MUST upgrade the wifi. Really a shame that you are charging for this, and it doesn't work about half the time. A real rip off, and not up to your standards. MANY guests were complaining about it, remarking it was the only negative on an otherwise perfect trip. It was particularly important to us because we were traveling with teens, and needed it to communicate locations on board. We were unable to do so.
Whew, got that out of the way! Everything else was wonderful. Service is terrific. The servers are friendly and attentive. The meals are very good. Of particular note is Toscana and Red Ginger -- spectacular meals. The ship is beautiful and clean and maintained perfectly. We had a penthouse suite, and really enjoyed the extra space and the butler.
We used two Oceania excursions. One was great, and the other was pretty bad. They probably need to improve the quality of their tour guides.
Extra room was worth it. Great room. Can't believe the size of the closet, or the bathroom!
