We too, tried Park-n-Cruise and found it to be EXCELLENT! They unloaded our baggage from the auto, and we had very little wait to get on the very short ride to the ship. The Park-n-Cruise van was exactly where they said it would be when we returned from our cruise, and once again, they helped load and unload our baggage. We gave the driver a small tip each time, and still saved $15 per DAY on parking.
We had occasion to check out the NEW Carnival pier, and IMO it's going to be much WORSE than the old pier for those of us who park and sail, if you plan on parking at the pier. The garage is MUCH further from the pier, and it looks to me like it's going to be a major PIA to park there. One more reason to use Park-n-Cruise or one of the other off site parking facilities!
