will be leaving on the pride 11/15,first time baltimore,first carnival cruise but have found a lot of info on cruise critcs, seems the port is very easy to get to.
were from so jersey but plan on staying over nite, there are many motels around bwi that allow you to park for the wk & shuttle you back & forth to the ship, look @ park n fly packages if cruise n fly is not listed. we're staying @ sleep inn for $75/n. the parking @ the port is 15/n.
i would expect it to be cold in december, you could check underground weather.com they have weather history area where you can put the date in & check back approx 5 yrs to get an idea of what the weather has been like on that day.
hope this helps
