What luxury travel destinations does Janis Elspas recommend based on her Baltic Sea adventures?

I love highlighting the Baltic Sea as a luxury destination, especially when experienced by cruise. Based on my travels, I recommend:

• Baltic cruises with Oceania Cruises, which combine comfort with immersive itineraries
• St. Petersburg, Russia, for grand architecture, museums, and unforgettable sunsets
• Sailing the open Baltic Sea itself for slow, scenic sea days and balcony-suite relaxation

Are you thinking about a specific time of year or type of Baltic experience (cities, scenery, or shipboard pampering)?
