If you get sick flying you are probably susceptible to motion sickness and a short cruise to the Bahamas will be good. Definitely get a balcony midship on decks 7,8 or 9. Talk to your doctor about meds you can take. Try to get a newer ship. Cruise Critic will give you specs on almost all ships. Don’t use the hot tubs and wash you hands frequently. Bring a passport and get trip insurance for medical.
