I wonder what their operating costs are for a 1 day trip? If the odds are high for getting into fish on a once in a lifetime trip then might not be so bad, it's not like they are just traveling across Devils Lake or Sak. If pretty much all you have to do is hop on the boat and pack clothes and other amenities you want then I don't think you are doing so bad. I will be interested to hear about and see photos from your trip.
I like doing as many things as possible for myself but I am learning that some things either aren't possible by myself, opportunities are getting more limited, specialized/the correct equipment isn't cheap either especially for once in awhile use, or I don't have a ton of time to spend figuring things out so some things are just going to cost me a little extra money.
