Before confirming your reservations, be sure the itinerary is not too demanding for you or your traveling companion. Visit your doctor and dentist before your trip. Schedule your appointments far enough in advance to allow time to take care of any health problems that need to be resolved before departure. If you're being treated for an ongoing medical condition, carry copies of your medical records when you travel in case you become ill. Get adequate sleep before and during your trip.
