I can't answer your question about which hotels offer a shuttle to the port, but your information about Amtrak service is incorrect. Baltimore Penn Station, BAL , is not at the airport, it is in downtown Baltimore. The BWI station is a different station located, as you would expect, at BWI airport. While all Amtrak trains stop at BAL not all stop at BWI, so in booking your train travel and hotel you need to take care about whether you need to book tickets to BWI or BAL based on what hotel you're staying at, and if the hotel is near BWI you have to be sure you're taking a train that stops at BWI.

What they mean is update the Global Entry record on line to match the new passport number. We just renewed our passports and that was the first thing we did after getting them. You log into the Global Entry website at https://ttp.dhs.gov/ .

Haven't been on that b2b but you will go through immigration, not customs, in Bar Harbor. Your cabin steward will move your luggage from one suite to the other . You don't take luggage off the ship on turnaround day. Because you clear immigration in Bar Harbor before Boston I expect you will not be required to disembark in Boston. Under similar circumstances on other cruises we have not had to disembark in the turnaround port.

I don't know why you paid $40 to Port Royal. The ride should have been no more than about $25 on the meter under normal circumstances for 1 -4 passengers Monday through Saturday .

You may not have to get off but you still have to be cleared by USCBP when you returned to the US from a foreign port on the b2b . If you weren't cleared by USCBP either on the ship or in the terminal someone either screwed up or perhaps CBP decided it would just accept the manifest as presented due to staffing considerations. Read my initial post carefully. I never said you always had to disembark. I said "It's generally done as you describe but can vary by port . In the US B2B passengers have to be cleared by CBP, which usually entails having to disembark and re board after the ship has been cleared although in some ports CBP might clear you in a lounge on board if the particular cruise terminal doesn't have adequate facilities" Note the words "generally" and "might". If having a single booking number were the controlling factor as you claimed in your first post than what is your explanation of why on one cruise with a single booking number you didn't need to get off but on the other you did? Does that not tell you a single booking number was not the reason one way or the other?
