We took the water taxi over to Atlantis, and it was SCARY. (IMHO)
It was pretty rickety, with those white plastic chairs on the deck. My sister & I laugh about it now, but at the time we kept looking at each other & rolling our eyes. We were glad to get on solid ground again!
And yes, you did still have quite a hike after you got off the boat. We "rested" a few times! We went to the beach next door to Atlantis, which was nice again, except for the hike over the HUGE sand dune in the 90+ degree weather. Anyway... Long story short, we took the taxi back.
