My thoughts exactly.
As compared to any other trip.
Extra cost for security? Not likely since it was aboard a secure ship.
Extra cost for flight to the ship? $1000 if not $10,000s cheaper than Airforce one.
Extra cost for participants? Everyone on the ship was already employed by the US Government.
If someone had the time and knowledge to, "put a pencil to it", I would bet this has been one of the least expensive speeches ever.
The DNC web page had Bush pushing old people in wheel chairs down a hill deplicted on a mock social security card, then they accused Bush of literally poisoning the water supply, then they accused Bush of cutting off poor peoples heat in the winter.
THE LOSERS NEVER CEASE TO AMAZE ME!!! They can met in back rooms from now to election day, they are toast they won't GET that America figured out they are socialist liars that represent good as bad, and bad as good. Even if they reinvented their party more centrist and less leftist no one will believe them-they are washed up and done and don't know it, yet.
