I just returned from a 2.5-week vacation yesterday, so I didn't know about the Baltic cruise price reduction until I returned. DCL is finally offering a price I would be willing to pay for their Baltic cruise, but I am already committed to another Europe cruise with my daughters. While I wouldn't have booked a balcony cabin in the first place, it would sure be worth the mega-bucks to give up a pricier cabin for the cat. 12, and get my butt to an outside deck to view the sailing into and out of Oslo and Stockholm! The price difference may be only money to some, but it would mean another cruise for me.
OTOH, you seem to have plenty of time. We are just the opposite and time is a bigger limiter than money for us. We are resource limited in different areas.
