Mile Mark Half Day FAQs
How long is the Mile Mark half day charter?
Four hours, at the time you choose.
How much does it cost?
$1,800 for the whole boat and crew, for up to 40 guests. Crew gratuity isn’t included; 20–25% is recommended.
What makes Mile Mark different?
It has room for up to 40 guests, more than any other boat in our fleet, so big families, reunions and groups can all go out together.
Can we choose what we do?
Yes. It’s your charter aboard Mile Mark: snorkel, beach time or both. We’re happy to accommodate any request as long as it doesn’t violate a National Park Service regulation.
Is food included? Can you cater?
Lunch isn’t included. You’re welcome to bring food and drinks (there’s an ice chest on board), or email info@caribbeanseaadventures.com to ask about having your charter catered.
We’ve never snorkeled. Is that OK?
Yes. Snorkel gear, a lesson and a guided tour are included, and a guide will be in the water with you. We’re happy to assist guests with physical limitations to the best of our ability.
What is the cancellation policy for private charters?
Cancel 48 hours or more before your charter for a 100% refund. Cancellations within 48 hours aren’t refundable, and no-shows are billed in full. If we cancel for weather, we’ll do everything we can to reschedule; if that doesn’t work, you get a full refund.
Our group is bigger than one boat. Can you help?
Yes. We can put more than one of our six boats on the water together. Call (340) 773-2628 to arrange a multi-boat departure.
