We did this today. We were picked up at the staging area and went by bus for a short ride to the starting point. There were clean bathrooms there and a place to purchase drinks for the ride. It takes about 90 minutes to complete the trip and you might even get a chance to steer the raft. We were given life jackets and could take them off after a spell. Always felt safe from the time we were picked up until dropped off back at the ship. A “thrill” ride it is not. But if you’re looking for a quiet, peaceful, ride down the Martha Brae river, this is great! My wife and I were on the first raft. There were 2 ships in port and a lot of people on this excursion. I certainly would do it again and highly recommend it.

Unfortunately, I'm a bit more blunt than Neesa.
What is your endgame?  Whether you mean to or not, you are coming across like you are expecting resolution in the form of a complete refund.
I'm sorry you and a 20 year friend are enemies now, but that's on the two of you not Royal Caribbean.  You and your former friend handed the staff on the ship a xxxx sandwich and they did the best they could. 
How good of friends were you if an argument while you were checking in for a cruise caused an irreparable rift?  
 
 
 
 

Wow. Just wow.
The only thing I see RCCL did that is questionable was to let you board in the first place.  
They gave you a second cabin.  You only paid for one.
RCCL is not responsible for your relationship.
Of all the ridiculous complaints I've seen from first time posters, this one takes the cake.
Suck it up buttercup.  You and your friend ruined your vacation... not RCCL.

Thank you

I fail to see where any of this is the fault of Royal Caribbean.
