A few weeks before our stay Maggie messaged wondering if we would be willing to switch boats b/c our boat was double booked. She said the boat we were getting was an "upgrade" & would cancel our booking if we didn't agree. We accepted. We never received check in instructions, apparently did need them b/c the door was unlocked. The boat had a HORRIBLE smell-unsure what, diesel or something like that. We opened the windows then left hoping to air it out. When we returned, the smell was just as strong. Unfortunately, it was too late to go somewhere else. We started noticing several air purifying bags hanging all over the place. There were also baseball hats hanging on the back of the door in the bathroom, leftovers in the freezer, and overall looked like things were shoved places to clean it up for the weekend. After a night of little sleep due to the smell & wondering if we should even be inhaling the fumes, we left. I messaged Maggie & she responded stating, "I understand, and I apologize that the smell is so strong. Boats can sometimes have an odor from fuel and other onboard systems. I realize it is unpleasant, and I appreciate you letting me know. We have been working with the marina to address the concern, and they have assured me that the boat is safe." Thankfully we got a full refund but very frustrating that she was aware of this problem & still let us stay there, even offering it has an "upgrade" after dbl booking us.Disappointing.
