My own story...
I'm not good enough to qualify for Nationals, but 2 of my kids did this year for the first time and so we went. While we've regularly gone to Regionals, but when you combine both trips (since the former is required) the all-in cost was about $3.5k. Unfortunately, one of the downsides of the cost is that my wife and youngest son stayed home so we could save a little money.
Nevertheless, being our first Nationals and our first trip to Boise my kids and I were really excited. Like many others we planned some activities around the skiing - we climbed a nearby mountain in the Boise Mountain range the day before our skiing. It was great way to kick off the trip and make a memory with my kids.
When we first walked on site one of the first people we saw was @MarcusBrown doing his thing and my kids immediately recognized him and totally flipped out. When we had a long layover in DEN on the way home, we killed time watching all of his Flowpoint videos. We got pictures with the pro skiers, sat for hours watching the best trick and jump skiers do their thing. We cheered, consoled and celebrated with our friends when they skied.
My kids were nervous and excited about their own skiing. My daughter skied her average in both events and my son tied his PB. There were great teaching moments. The #2 seed in my daughters division missed her gates on her opening pass. Heartbreaking. 5 hours later I'm buying a raffle ticket from her and she's all smiles.
The skier right after my son fell at 1 ball. His dad was on the shore consoling him. As we watched all that unfold, I took the time to have a conversation with my son about what happened and what it means. You can't duplicate these conversations anywhere else.
I supported the sponsors and spent about $1k in equipment (3 event skiing is expensive!) so you can add that to to the $3.5k total above.
When it was time to leave, neither one of my kids wanted to leave. We just had the time of our life - and it wouldn't necessarily have improved if we skied 2 more rounds.
I can't measure my ROI in dollars and cents, but I can in another way. We got home last night at 1:45am. When my daughter woke up this morning she asked me if we were going to the lake today.
Now I totally understand if I had been going to Nationals for 25+ years I might become bored with the idea of getting 35th place out of 40 skiers and not want to keep spending that kind of money to get a predictable result. But I don't think that necessarily means Nationals is broken.
I don't think Nationals can be all things to all skiers. I don't think it's possible to have one tournament be ultra-competitive, have multiple rounds, include non-qualified skiers, showcase professional skiers, be family friendly, convenient, cost effective and over a 3-4 day weekend.
There is a time and a place for other formats like Buckeye Buoy Tour, the BOS Cash Prize, Pro-Ams, Big Dawg, etc. to do accomplish those other goals outside of the Nationals format. If we want to debate the right format for Nationals (i.e. sudden death vs. multiple rounds) that's fine, but I don't think the goal should be to try and shoehorn the other formats and take away from the prestige of the event itself.
