Thanks, Blake, for your suggestions. Some things we have already considered, otherwise would not be considering this. We are using some airfare watch apps and such but I wasn't aware of the google and bing tools so will definitely consider this. Right now, by our calcuations, going with a plan like this does allow for us to break even when considering lodging, food, drink, etc.. We do enjoy the AI experience but have also done otherwise.

Will exploring and pass info on and eventual outcome.

Will continue to welcome any and all input from forum friends.
