Booking Excursions at the Pier

I am on the Fascination next month and have never been to St. Kitts. I am usually one of those people who likes to figure out what I want to do last minute. Is this like most other ports where there are Vender stands all over to book excursions on the Pier?

There will be people at Port Zante offering their services for tours and excursions. According to cruisetimetables.com your ship will be the only ship in port that day
