How do Cuomo & Co. rationalize that day camps are safer than overnight camps? Instead of camp being isolated, we have the same hundreds of kids going to camp daily, then returning home at night to their families (instead of staying on campus). I truly don't see how from a medical and scientific perspective this makes any sense.
What you say does make sense to me, and I had also expected that day camps would be considered more dangerous. But the risk depends on both the frequency and duration of contacts, and duration may be more critical. If a single infected camper or counselor goes to sleep for 8 hours in a room with ten others, they all may be infected by morning.
There is also the problem of quarantining even just one case in the typical camp infirmary. Quarantining several may be impossible.
There might also be concern that the small hospitals in rural areas where camps are found wouldn't be able to cope with an outbreak.
Finally, there might be concern about sending kids back home if an outbreak were to occur. Parents can quickly pick up a sick child from day camp, while they may be many hours away from a sleepaway camp.

JCC day camp here had 3 covid cases in the preschool camp and sent the kids home for a week while sanitizing. The following week 2 more cases occurred in the older camp, and again those kids were sent home. It's hard to imagine being able to send kids back and forth like this from a sleepaway camp, should an outbreak occur.
