Deal watch: Azamara Club Cruises offers free upgrades

A balcony cabin for the price of an interior cabin? That's the latest offer from Azamara Club Cruises.

The upscale operator is offering a two-category cabin upgrade to customers who book now for the coming winter.

The new offer is good with nearly all sailings of the line's two ships departing from October 2014 to December 2015.

Bookings must be made by May 31.

Azamara Club Cruises' two vessels, the Azamara Quest and Azamara Journey, carry 694 passengers a piece. For a deck-by-deck look at one of the ships, click through the carousel below.
