Log on to Amtrak's Web site and select the Miami and Jacksonville stations from the station lists to search for schedules, routes and fares.
Decide which amenities you would like included. Since the trip to Jacksonville is approximately 10 hours, you might want to reserve a sleeper car for an additional price or a spot in the dining car for a nice meal.
Book your ticket when you've found the best schedule and fare for you by entering your credit card information into Amtrak's secure server.
Pack reading materials, games and toys in your carry-on to help keep young children amused. Amtrak sells a children's activity book on-board that costs about $2. Don't forget a book or magazine for yourself. Other useful things to bring on board include a pillow and light blanket, plus a camera and/or binoculars for spotting landmarks and scenery along the way.
Reserve a personal handheld DVD player ahead of time. For a reasonable price, Amtrak offers them pre-loaded with 12 new-release blockbuster movies, as well as music and popular television shows.
Check on your reservation before your travel date to confirm your schedule. Make sure you bring your printed itinerary and confirmation with you when you arrive at Miami's train station on your departure date.
Arrive at Miami's train station well in advance of your time of departure so you have time to check in, pass any necessary security points and check additional luggage. You are permitted two carry-ons per passenger.
Remind the ticket attendant of any special requests when you check in. If you are disabled, have food allergies or any other medical needs for your travel, now is the time to be sure they are arranged.
Get comfortable. Settle in for your journey with a pillow or a Jacksonville travel guide, and enjoy your train trip. Arrive refreshed at your destination, collect your bags and head off to your accommodations or meeting.
