My wife and I just came off a 10 day cruise on the Explorer last week. This was our tenth time on the Explorer since 8/2007.
The cruise port is one of the only things I dislike. The car line can be very long to the drop off point. There are two lanes that funnel to one and if you get there when passengers are trying to get picked up it can become controlled chaos. You have to take a bus from the drop off/registration building to the ship.
When we board the ship it is like old home week. We are recognized by many of the crew and they make you feel special. How they remember you and your names after a year is amazing.
Excellent cabin, spacious, clean and great service.
