Please explain exactly what I said that you disagree with.
"I'd have very mixed feelings.
There are literally thousands of hours of logistical work that went into organizing our small kosher cruise. It would seem to be unfair if someone came along and took advantage of a minyan without helping to defray the cost of making that minyan on a boat. A minyan is a small part of the cost of a kosher program, but it's part of the package and getting a torah onboard and obtaining space onboard is no small feat.
OTOH how do you say no to a fellow Jew wanting to daven with a minyan?
At any rate, this happens at Pesach programs all the time where people either sneak in for minyanim, lectures, and entertainment or they ask if they can attend without being part of the program. I think it reflects poorly on someone who would put himself in that situation."
"You may think you're being a good Jew by sneaking in and davening in said minyan, but I'd posit that you are not. These are businesses offering a minyan to meet their paying clients needs, not community shuls. You are gaming the system at another Jew's expense."
