If you had 100,000-500,000 miles for a Millenium (anytime in 2000) dream trip. . . what dream trip for two might you create?

160K Two Delta/Air France tickets to Tahiti?
395K Cruise on the Radisson Seven Seas around Tahiti and Bora Bora (AE/MM)?
30K A trip with meals and a private cabin up the California coast to Vancouver on Amtrak (Alaska Airlines)?

How far could you stretch the points? And, could you travel (hotel, cruise, air meals, whatever) mostly on points?

I'm thinking Katmandu, what about you
