I am planning my travel to Saba from Toronto and I have a quick question. There are number of ideal flights (single day, cost-effective) that arrive at St. Maarten at 3:09 pm. Is this enough time to clear immigration and get to the dock for 4:30 pm? I called the ferry service and the lady said she wasn't really sure, that it would be close. Is it worth a shot? Any insight from experienced travelers would be greatly appreciated.
