If I just order something small, like coffee or a dessert, then I leave $2.  A meal up to $5.

It was amazing, you can read about it here! 
 

This same thing just happened to me for my Norway Cruise last week. Unless you get a cancellation email, I wouldn't be too worried. If it continues to show up in your calendar, it's booked.

We loved Victoria.  Amazingly beautiful place.
 
When you get off the ship you'll find about a 5 min walk (maybe less) to get onto the road.  You'll be at a giant sundial (Ogden Point).  To your right is a neat rocky beach/cove which is very picturesque in the morning.  If you walk left (north) and stay on the road, you'll be walking past some residences and after about 1km (2/3 mile) see Fisherman's Wharf.  It's hard to miss, but if you have any doubt you'll find many locals walking docs and such - everyone is incredibly friendly.  I'm sure you could get a car for this walk, but it's an easy and very pretty walk through a not at all touristy area, so we liked it.
 
Once at Fisherman's Wharf, walk around, as it's full of houseboats turned B&Bs, restaurants, etc.  Just a neat little area.  From there, you can take a water taxi to the harbor for around $5/pp (the area with the Empress hotel, visitors bureau, many shops and restaurants, etc).  This is likely where you'll want to spend much of your day.  The visitor's center is awesome, and they'll help you get to the gardens, or anything else you're looking for.  Plenty to do there, and I'd also recommend a place we check out, Vista-18 atop Chateau Victoria.  Great views, drinks, and snacks.
 
I could go on about Victoria for some time, it's really a great place.  Let me know if you have any other questions.

If you are looking for a similar experience, last July we did this.
Onboard Experience - Royal Caribbean International
The ATVs are two person vehicles and overall I think it was good excursion.

This is where I saw it.
Onboard Experience - Royal Caribbean International
This is the generic description of the excursion on RCL website.  If you look in 'Important notes' it says 'parties under 3 guests will share a jeep'.  If it doesn't say so on your cruise planner booking, maybe that is no longer the case.

I was on a similar excursion in Cozumel in the pre-pandemic era, and my wife and I were paired with another couple.  I was the only one who could drive stick, so that pretty much decided the driving situation.  Obviously a different company in another time, but RCI setting up a tour like that has precedence.

I can't imagine the drama of putting two couples into a Jeep and then having to have them decide who is going to drive.  I, personally, would not want to ride in a vehicle with some other random, unvetted person, driving.  I would be surprised if they did that, but you could call the company and ask.  The number is on the door of the Jeep in the photo in the Cruise Planner (907)945-3141.
