We arrived in Acapulco around 10am, cleared customs, boarded our Princess transfer bus, and were off to the port in about 45 minutes. The ride to the port took about an hour. Upon arrival at the pier around noon, we were happy to see no lines anywhere! We walked right up to the counter to check in and then right onto the ship with no wait. If you use the Princess transfer from the airport, your luggage is taken at the airport and the next time you see it is in your cabin; I liked that. Quickest embarkation we've ever experienced. We did get back off the ship after lunch to check out Acapulco a bit, and picked up a bottle of local wine and some champagne.
We had a mini suite on the Dolphin deck which was very nice; carpet looked new and most things were in good shape. Nice large balcony (though uncovered) with 4 chairs and a table. Later in the day when we saw our room steward we asked for our glass of champagne (which was delivered promptly) and for robes (not impressed with the robes that showed up the next day).
Two in our group who stayed in the mini suite farther aft had older carpet than the 3 cabins the rest of us had on Dolphin deck mid-ship section. Different design on the carpet, and theirs had some stains too. Their tiles in the bathroom weren't in good shape either. Note that if you're over 6'3" your hair will clean the ceiling over the bathtub!
