Double-elims with that format could go a LONG time if any decently skilled players are there. For reference, we ran a single-game, double-elim two weeks ago and 40 people took 5.5 hours with four games cranking almost non-stop. Of course, several league/tournament players were there so the game times were longer than what you can expect, however, 24 players on one game...

But if it's all day, you're probably fine. It also means potentially long waits between games, and people might lose interest.

I would not advertise the low score prizes in advance, otherwise you'll get some sneaky sneakerson deliberately tilting out to get the low score.

If you want some free software to run it, this works good:

I've done a lot of pin golfs. I ran one tonight, actually.

The typical pin golf is there's a score to get on the game and the player tries to get the score in the FEWEST number of balls they can. Just like golf - you're trying to get the golf ball in the cup with the fewest number of strokes. So balls = strokes.

In many I've seen, the goal is the replay score, but that can be tough, especially for newbies, so you might want to go lower.

You need to set a stroke limit. For only two games, 6 is good. That means if they don't get the score in the first game, they start a second. To make things faster, I let players add their first game score to the second. Example: On Twilight Zone, score 100 Million. The player ends ball 3 with only 85 Million. They start a new game and now they just need 15 more million to get the goal. If they get it on the first ball of their second game, their score is 4 for that hole. You need score sheets to record the carry over score. Likewise, I have players round to nearest significant digit (nearest Million on TZ, but on an EM it might nearest thousand or hundred). That makes score keeping much easier/faster.

When I try to figure out pingolf goals, I play a few games. When I can get the goal in 3 balls, that means a super good player will get it in less, a super n00b will get it in more.

You can toughen up goals in the finals, or else you might get a lot of ties.

I let players play EBs, and the EB doesn't count against their stroke totals. In most tourney formats, EBs are not allowed, so pin golf is a nice break from that.

The advantage of pin golf is that the better players will finish faster. You have much less worry of epic long games. Soon as they hit the goal, they stop playing.

The biggest disadvantage of pingolf is novices just don't get it. You will have to explain many times over how it works and you'll have delays as a result.
