First, this is a really great service to get to different parts of the inner harbor. Employees are friendly and professional.
I stupidly bought the 2-day unlimited for my family of 4. Due to bad weather (not the fault of Baltimore Water Taxi) 2 days in a row, we only got 2 rides out of the tickets.
Worse than that, both times that we were stranded (again, due to bad weather, which is not the fault of the company), it was impossible to find out online about the stopped service. Though the ticket may say that BWT posts updates on Twitter and Facebook, they do not. I called the service to ask about when service might be resumed, and I was told to check Facebook and Twitter. No update had been posted.
I'm short, if BWT would simply post when service is suspended due to bad weather, I would rate this service much higher.
