We just did the EIS-MIA flight and it was amazing. Our taxi driver told us it is the most reliable flight the airport has. As others have noted the Sky Tram is down so you will definitely get your exercise going from gate to gate.

I will also say that the ferry ride to and from St. Thomas has also improved a lot. Our last few ferry rides have been comfortable and on time. This last one (from STT to Road Town) I was actually cold because Road Town Fast ferry has the air conditioning turned up so high in the enclosed cabin but the ride was smooth even in some semi-heavy seas.
