If traveling to Manhattan cruise terminal from SE PA, we have found the easiest, least stress for us is Transbridge Bus Line. That go from Lehigh Valley Airport (ABE -- Allentown, Bethlehem, Easton). They do a round trip for Seniors to the cruise terminal on Embarkation day , then back to ABE on disembark day. You can include parking at airport for $5 per day; 1st 3 days are free. You give them you luggage when you get on bus and you see it again when delivered to your cabin. ( I still take a picture of luggage before we hand it over, just in case!)
