Imagine TopGolf, but with steeper prices and a less enjoyable experience. If that doesn’t sound appealing, you’re not alone — yet that’s exactly what Upper Deck Golf at Coors Field delivered this past weekend.

Upper Deck Golf bills itself as “a once-in-a-lifetime golfing experience inside the most legendary stadiums and ballparks across the country.”

Whether Coors Field qualifies as “legendary” beyond its reputation as a hitter’s park is debatable, but the chance to tee off in an empty baseball stadium certainly sounded like a unique opportunity.

Was it worth the nearly $120 per person (after tax) we paid? That’s where the regret kicks in.

After hearing about the event, I quickly signed up for the waitlist to ensure I could grab tickets as soon as they were available.

Tickets went live.

However, using typical scarcity tactics like “limited availability” and “once-in-a-lifetime” to drive urgency, floundered. Even on the final day, tee times were still available; so much for the “limited availability.”

Once you’re in the portal to book a tee time, Upper Deck Golf pushes you to upgrade to a “VIP” package for an additional $60. This includes entries into the putting, driving, and closest-to-the-pin challenges (which can also be purchased à la carte for $10 each), as well as unlimited food and drinks in the “clubhouse” and four extra mulligan balls for the nine-hole course.

I opted for the standard package.

A quick tip: Once you’ve bought your tickets, there’s no flexibility and your reservation is set in stone. There are no refunds or rescheduling, and you must book for at least two people, with party sizes only in multiples of two. You can’t book a group of three or five. We had trouble finding a fourth person for our group, but Upper Deck Golf didn’t mind taking our money anyway.

The silver lining? We got to split the extra player’s balls as mulligans. Even though I was a few minutes late due to classic I-25 traffic, the event staff were unfazed, and check-in was friendly and smooth.

If you skip the VIP option, expect typical stadium pricing for food and drinks. Our group spent about $10 per beer. The staff, mostly Coors Field regulars, were as friendly and welcoming as they were during Rockies games.

The nine-hole course featured a variety of angles, distances, and elevation changes for chip shots around the stadium. However, club choices were limited; just three wedges (50-52 degrees).

There was also an indoor putting challenge, but since it required an extra $10 and I wasn’t doing the VIP experience, I passed on it despite my love for mini golf.

You can bring your clubs, but no golf bags are allowed inside the stadium. Only sand wedges, pitching wedges, 9 and 8 irons are permitted. For safety reasons, no drivers, fairway metals, or low irons are allowed as well. Before purchasing tickets, I recommend thoroughly reading the FAQs on the event organizer’s website.

When you manage to hit one of the targets (which my limited golf skills only allowed me to do a few times), they light up with LED lights, offering a brief dopamine hit. Unlike TopGolf, however, you must manually keep your score with a pencil and paper scorecard — just like in the old days.

For experienced golfers, this might seem like a minor inconvenience — golf is expensive and paper scorecards are nothing new. But this event was aimed at casual golfers like me, and judging by the crowd at my session, I wasn’t alone.

One important factor is: Weather. The event runs “rain or shine,” so plan accordingly. We were lucky to have a gorgeous Colorado fall day with sunshine and a light breeze, but those who booked tee times that coincided with Friday’s cold and windy weather probably didn’t have such a pleasant experience.

Was it worth it? Compared to a similar experience at TopGolf, I’d say no. The weekend before, my group spent about $68 per person for 90 minutes at TopGolf Centennial. That price included some food and drinks (two pitchers of beer), a wider variety of clubs, different game modes, and no need to reserve ahead of time.

Still, Upper Deck Golf offers something TopGolf can’t: bragging rights. The chance to play golf in a Major League Baseball stadium is a unique experience that most of your friends can’t say they’ve had—at least until the event returns next year.
