Cruise in Lake Michigan?

lots of options if you drive most of the trip & take a short ferry ride but somehow I do not think that is what the OP had in mind :D

 

Maybe they will come back

Well, given the parameters of the OP, the Badger *is* the best option. Only lines working the Great Lakes in 2015 are Blount and Pearl Seas, and neither are suitable for children.

Many posters have made assumptions as to the willingness (or not) of the OP to spend the money it takes - he may or may not understand the roughly $1200/day cost on Pearl, slightly less for Blount . . . . . but again, I wouldn't dream of taking anyone under 60 years on either of these.

(Done Blount, Pearl Mist, Badger, etc.)

Saint Laurent is doing the Great Lakes as well but none are going to be budget friendly

In any case the OP has not returned here
