No formal link but bring your return ticket with you to the Bahama's.
Immigration officials will want to see proof of your date of return before they let you back in.
Visa waiver program is no a problem, they just want to verify that you are not going back and forth to the Bahama's to get 90 day extensions.
Where will you be flying out of?
