I would definitely recommend the purchase of the go Miami card, we saved approx. 500 between us. We used it over our 14 day holiday. Note that the key west trip only accounts for the bus trip nothing else, on some trips you have to pre-book and visit the organizer to get your card swiped which can be inconvenient depending on where you are staying.

This is the first real vacation my family has taken in the past 15 years, and I would recommend this card to everyone. The only problem we ran into was not enough hours in the day to do all the things we wanted to do that were available with this card. Worth every penny!

I found that it was so much trouble to pick up the Go Miami card and that took away some of our day. We only managed to get to 2 places so it wasn't any cheaper than going without the card. I don't think I would waste my time with Viator again because you can go right to the card company and they will send you your cards in the first place.
