Now that I know the price of Marquesas Islands and there is no free air...I'm afraid that won't be an option.
Also, thanks to Andi bringing up something that should have been obvious to me.... I'm concerned that it may be difficult to do the back to back. I'd be all attached to the friends I meet on the first week and the 2nd week might be a bit of a let down.
Maybe a pre or post cruise is our best option.
