The Portland Spirit Boat is great. Get in on it have you a nice dinner and a ride down the Columbia River or on her sister ship which I believe goes down the Williamette (It might be the other way around).
The boat is very nice, this would be a great thing to do with your honey if you are wanting to get out and try something new or just want to get out and have a little romance.
The staff that work on the boats are great, friendly and outgoing and will help you with whatever you need.
Call in advance and make your reservations because sometimes they can be booked way out in advance.
This is just a great thing to do, if you like the water and boats!!
