Can’t be fair to everyone in a large family

Noah has an opportunity to camp out in the Okefenokee for 5 days and 4 nights. The estimated cost doubled on me last night. I have concerns about the trip including:

1. Can I actually take 5 days off?
2. Shouldn’t that money go elsewhere?
3. My wife said that I was to make the decision and when I said, "we are going" she replied, "whatever" which in wife-speak means "wrong answer dumbass."
4. Are we properly equipped for this kind of trip?
5. If we pass, are we giving up a once in a lifetime opportunity (apparently this is a hard trip to book)?
6. Can Noah handle this trip?
7. Childcare during Cathy’s meetings and events

I feel like my gut is saying not to do this trip but I also think I am misreading my reasons for saying no. I have to decide today.
