Not sure about parking at the hotel, but parking at port is $10 a day.
The do sell cigs on board, not sure which brands, since I don't smoke. You can also buy them at port, just about every other shop sells them.
Coke products on the ship, but you can bring your own sodas, and store them in the cooler in your stateroom--a little tip is to bring them on pre-chilled, since it's a cooler not a fridge. Otherwise it takes forever to get them to cool. But ice is provided all the time, at the drink station, or you can have your stateroom host/hostess bring it to your room throughout the day.
Pins are on board---they sell them and had trading hours on my past cruises. Usually all the crew working in the gift shops were wearing lanyards.
As far as dining rotation, I have always traveled with just adults and have gotten the TAPT rotation on my past 3 4 day cruises. I believe that is the usual rotation for adult only cruises, but realisticly you can get any. I had late seating for all my cruises as well. As far as entertainment, I really enjoyed the shows and the first run movies. They had serveral interesting daytime activities (ice sculpture demo; trivia contests; putting contests; animator lectures; pool activities; master chef demo's; spa demos; fitness classes; bingo and more--and that was just the 4 day!) I loved the evening karakoe; 70's night, 80's time warp, match your mate, and more.
There are tons of things to do. You can dance, or sit and listen to nice jazz music, watch a good movie, read and watch the ocean at night on deck 4, or take a evening dip in the hot tub.
You'll have a blast!
