We booked the Best of Aruba with the ship. Good tour for a decent price.
We walked across the bridge and booked a tour in an open van. It was good and we saw the entire island.
We booked at the port. The tour was good but we had price issues in that we were quoted one price to be paid at the end of the tour, and then the price changed higher at the end. Be careful, bargain well.
Just got off the ship, walked around for an hour and back on the ship, no bargains to be had.
