I had to cancel, which I did more than 24 hours in advance. I think the credit voucher system is a total rip off. Hotels DO provide refunds if the room is cancelled up to the day before your stay. To expect boaters to keep track of a piece of paper - the credit voucher - for a year in order to get credit is unreasonable and ridiculous. You should have better customer service and provide full refunds up to a reasonable advance notice, just like all other marinas in the area. VERY DISAPPOINTED.
