I wouldn't recommend the ferry for the return trip if you are prone to seasickness. Otherwise - it's great. Beats driving.

Get to port early to get best seats.

relax and enjoy had a great time

T efficient way to get a taste of Key West. The best option would be to stay overnight and catch the ferry back the next day.

Bring something to do as it is three hours. Bring a book or magazine.

1st time out of Marco and surprised only took 3:20 port to port. Temp was perfect on boat. I remember one of the trips from Ft Myers freezing on boat with air turned too low. I would definitely go back out of Marco after this trip. Gives you about 5 hours in Key West if you do the single day trip which was perfect. You just miss the sunset.

If you get car sick or have motion sickness take something before going. If you have a group get there a little early to get seats together. Bring a sweatshirt if sitting inside. A/C very high in morning.

Take your motion sickness meds,etc. for the trip as a precaution otherwise we enjoyed the trip

Be sure to take Bonine if at all subject to motion sickness. Even with calmer seas there is a rolling motion. There are several tour trips to take on the island. I recommend the bus tour since you can get on and off at several places. The conch train tour has only 4 stops.
