One thing I've noticed for sure is that comps in some parts of the country can be very different from comps in others. This goes for NDCA, USA Dance, and collegiate competitions.
Out here in the San Francisco Bay Area, the organizers try really hard to treat everyone well: Pro/Ams, Pros, and Amateurs. It's a delicate balancing act. But good things have been happening over the years that I've been dancing out here.
Take the San Francisco Open as just one good example of a well-balanced NDCA competition out here. No amateur events are during the day on Friday, except for the "solo" competitions. I dance Standard, and the Pre-Novice (Closed Syllabus) Standard and the Novice (Open Syllabus) Standard are both held on Saturday afternoon. Ballroom tickets for that time are $15 per person (which is in the range that my friends can pay) and the entry fees are $15 per event. So, for me and my partner to dance three events (Closed Syllabus W/Q, Closed Syllabus T/F, and Novice Standard W/F/Q) will cost a grand total of $75 for us as a couple:
2 entry tickets @ $15 = $30
3 event fees @ $15 = $45
Divided by two, that's $37.50 per person for the biggest and best-run NDCA competition in our area. We'll definitely get semi-finals in our events, and usually get quarter-finals.
Our USA Dance chapter hosts low-cost competitions, the nearest equivalent in size to the SF Open would be our Regional competition that we do in odd-numbered years. That cost $25 per person, so about 1/3rd less. So yeah, there can be a pretty big difference in price between our el-cheapo events and what the SF Open offers, but even at $37.50 per person we aren't being gouged.
Other local competitions out here cost about the same. The International Grand Ball is a bit more expensive for amateurs, and the collegiate competitions are a bit less for adult non-students. The wost anyone has done scheduling-wise to the amateurs is that for the past two years, the Closed Syllabus amateur events at the SF Open were held on Friday afternoon. I think that really cut into the attendance (I recall there used to be quarter-finals, and the numbers dropped in half when they were moved from Friday night to Friday afternoon). Fortunately the organizers have changed this, so I'm hoping it will be good-sized again this year.
(Heck, I'm hoping I can actually dance it it...K.'s leg muscle is still not good. We tried dancing on it after six weeks of rest and he hurt it again. We might take all of February off, which does not bode well for us being able to do the SF Open. Sigh. I love that competition!)
