For Baltic cruise travelers, history's biggest-ever expansion of the European Union is a big boon. Ten countries joined the 15-member organization and, in conjunction with that, cruise lines looking for more variety on the standard Baltic itinerary added cities in three of the EU's picks -- Estonia, Latvia and Lithuania -- as ports of call.

Estonia, whose Tallinn is so charmingly restored it's easy to feel like you're on a Hollywood film set, has already become a Baltic itinerary staple. There's a renewed interest in Riga and in Lithuania as well (although ports in Lithuania are limited to cruises with more exotic itineraries).

Other relatively new additions to Baltic cruises include Poland's Gdansk and Gdynia. Warnemunde, in Germany, is becoming a staple because the port town offers direct train transportation to Berlin (though it's a long day).

Additional changes are afoot, too, even on the Baltic's cornerstone "capital highlights" itineraries (the Stockholm-Copenhagen-Oslo-Helsinki run). St. Petersburg, which is always a major port of call on these journeys, is more glorious than ever before as a result of a massive restoration that preceded last year's 300th birthday celebration.

As a result of these evolutions, cruise travelers who once considered a Baltic voyage to be a once-in-a-lifetime experience, are coming back for another go.

In other Northern Europe regions -- the Norwegian fjords and islands of the North Atlantic -- changes may not be quite so revolutionary, but passengers, whether first-time visitors or veterans, will see some differences.

Read on for our take on the most prominent trends impacting the Northern Europe/Baltic cruise experience.

Longer Stays in St. Petersburg
While most cruise lines feature one-night, two-day visits to St. Petersburg, some are adding a second night and a third day.

Longer Season
Prime Northern Europe/Baltic season was once pretty much limited to July and August (save for September transatlantic crossings); voyages now begin in May and run well into September.

Emergence of Shorter Itineraries
Used to be -- and mostly still is -- that a Baltic cruise required a 10- to 14-night commitment. Now a handful of lines, such as Regent Seven Seas Cruises, are offering seven-night voyages.

Introduction of Mega Ships
Princess Cruises has put its mid-sized vessels in this region for years; over the past few years, however, its mammoth Grand-class ships, such as Grand Princess and Star Princess, have served the region.

Offbeat itineraries
Smaller-ship luxury lines are getting more adventurous (if not slightly wacky). Iceland and Greenland are among those in great demand as are the more offbeat ports in the Bay of Bothnia, which lines the coasts of Sweden and Finland.

When to Go
This region's cruising season is quite similar to that of Alaska. You'll find the greatest choice of itineraries occurs during the prime months of July and August, but intrepid cruisers can also take advantage of early- and late-season deals during May and June and then again in September. The benefits of off-peak cruising here go beyond financial incentives -- you'll also bypass crowds in some of the region's major European capitals.

Choose A Cruise
For first-timers, a big-ship "Baltic capitals" voyage is a great way to get a first-glance overview. Lines like Celebrity, Royal Caribbean, Princess, Holland America, Cunard, P&O, Oceania, Seabourn, Silversea and Crystal offer "highlights" voyages, which typically last from 12 nights to two weeks. Itineraries rarely vary -- expect to spend a couple of days in St. Petersburg, and then a day apiece at Copenhagen, Oslo, Stockholm, Helsinki and Tallinn. Some do venture to Warnemunde (for Berlin) and Gdansk as well.

Two cruise lines are bucking the longer-itinerary-trend. CostaAtlantica features a seven-night Baltic voyage that calls at Stockholm, Helsinki, St. Petersburg and Tallinn. The prime disadvantage is that the ship's stop at St. Petersburg lasts a mere four hours. RSSC's Voyager also offers the Baltic itinerary within a week's time frame; its trip, in contrast, spends three days in St. Petersburg and full days in Tallinn and Helsinki. Both cruise lines offer a handful of similarly port-intensive week-long voyages to the Norwegian fjords.

Beyond the Basics
Where ships once incorporated calls at North Atlantic isles like the Faroe Islands -- Greenland and Iceland as necessary diversions on a seasonal transatlantic repositioning -- some lines are now offering more in-depth itineraries, and they're not limited to crossings.
