Took a cab each way. Very easy. Cost depends on number of people. It was $8 pp going and $10 pp returning.
We arrived at 10:15 am. This experience was awesome withe planes landing almost on our heads. Lucky to see KLM 747. Great pictures using sports mode on my camera. Also watched people plane surf on chain link fence as planes took off. We didn't do this as it is dangerous. Ate lunch at nearby Sunset Bar and Grill. Great fish sandwich.
Had cab drop us in Philipsburg for shopping and then took leisurely walk back to ship,
