Can I stay in the Bahamas overnight if I use the ferry or am I expected to return the same day?

Thank you, so I can book a one way each way or do I need to get the round trip and choose my return date?

To be precise U.S. nationals can stay for up to eight months without a Visa.

you can stay as long as you want

You can return the same day or stay as long as you allow to. Last time I went stay for 3 days, it was really worthy

yes you can stay buy make sure check when the boat is not sailing so you could work around that

You can stay overnight without a visa if you a USA national. For other countries nationality I would inquire with your embassy or Google search.

Yes, check out the website and they have ferry/hotel packages.

Yes you can take your passports i would book them together but im Shure you can di it separately if you want to
