The beer is probably from the brewery that is only a few blocks from the Radisson, in downtown. Maybe they have a pipe right to the boat to fill up before they leave the dock.
No transport cost.
There is also a Buffet Dinner cruise, with Grilled Shrimp & Chicken, on Friday night for $37.95, or 62 yr and older, $35.95, 7:30-9:30pm.
Neither of these will have the "lock-thru". You would need to have the 2.5 hr or longer for the "Lock-thru", of the locks.
We have been on the dinner cruise a few times, that last being about 5 years ago. Always enjoyable to see the bluffs from the river and watch the other boats. Lots of pleasure craft on weekends.
