Lighthouse Cruise Cancelled

June 20, 2019


Unfortunately, Cross Sound Ferry has cancelled the Lighthouse Cruise for today (due to foggy weather). We are sorry for any inconvenience. We will be refunding your ticket purchases. Please note: $22.50 of your payment went to Cross Sound Ferry and $7.50 was a fundraiser for Southold Historical Society. We realize you paid $30 per adult (or $31.50 with the processing fee if you paid via Paypal). Please email us back with your preference of either donating the $7.50 difference (and receive a refund of $22.50) or if you would like a full refund of $30 (I am sorry but we cannot refund the processing fee of $1.50). Feel free to email us at info@southoldhistorical.org. Sorry we will miss out on spending the afternoon with you all. Thank you for your understanding and support!
