Exchange currency at the airport?

As you clear customs and the time share sharks, on your left there is a bank and a money exchange. If the bank is open it has the best rates (personally I would get more than $200 exchanged), the money exchange is open longer with decent exchange rates. The bank should be open at 4:30PM.

I always exchange US money at the airport bank. Best rates around.I thought that they were open until 5:00 p.m.
