My party flew into San Diego, the morning of the cruise and took a taxi from the airport over to the cruise ship terminal area. We arrived around 10:30am walked up, dropped off our luggage and then walked to the North along the pier to have lunch at Anthony's Grotto (my favorite in San Diego - awesome clam chowder).
After lunch, we walked back to the cruise terminal - it was around 11:45am by now and HOLY cow - was there a line - going out the terminal - and once we weaved our way into the terminal - about 20 minutes later - it was standing in lines for about and hour and a half (little less or more, can't remember exactly - but it was of slow standing/walking - not good on the back).
Once we got up to the counter, as we entered the Platinum/Emerald line - it went a bit faster and we were on the ship by 2pm. We had a light snack and walked around to check out the Vision. So quaint and little compared to the bigger ships.
I enjoyed the cabin, but learned that being at the front during rocky waters was not a great idea. Will definitely go more mid-ship in the future.
