This was our third cruise with Oceania (all on the Marina) and around 18th overall, and the first where I've felt the need to write a review on this site.
Embarkation: Not a great start. In Lima we waited an hour in line in the afternoon sun and heat at the entrance to the port to get on a bus to the ship. The only Oceania presence was a small canopy with the logo on it where you finally got on the bus. At no time did anyone from the cruise show up with water, shade, or an explanation. Passengers were basically left on their own.
Once on the bus we were driven to the ship only to find another lineup on the dock. Again it took an hour to get on the ship. Eventually they handed out water and then opened the a second gangway for passengers (it was being used solely for luggage at first).
