Do not take watet taxi. They drop you off too far & you have to walk a distance. They don't tell you that. We made that mistake the first time. This time we took a cab (10 min) & they dropped us off at the front door. As for "waltzing" in, maybe be just got lucky both times but I must admit it really is quite simple. Others have told us about paying $25.00, etc. but both times we walked around the gorund, toured the aquarium, the dig, etc. without anyone stopping us. Hey what the heck try it.
