The best honeymoon travel package I could find in Peru was for 16 days and 15 nights. The package gets you a tour of the country with a new location just about every day. Fully private with all accommodations in honeymoon suites. You also get romantic dinners for two, and first class trains to Puno. They even bring you out to a secluded beach in Mancora! Mazel tov on your impending nuptials!
