Getting to the port can be a little tricky. Parking was easy but getting out was not so easy as there was construction going on. Other than that, it's a good port.
We loved the Butterfly Conservatory. However, it can be a little pricey unless you have a discount coupon or something. The bus drivers have discount coupons but I bought a butterfly scarf at one of the shops (a butterfly shop) where we first got off the shuttle coming from the boat and she gave me 3 discount coupons that gave us admission for $6.50 each which was a good deal. I believe normal adult admission is somewhere around $18.
City Tour Rating:
A good way to get around the City. Can jump on/off. There were 8 stops.
