I went on 10 cruises this year - here are the shifts that surprised me

My calendar was dominated by the Caribbean, because it's the busiest and most profitable region for cruise lines. However, these ships were launched with good intentions, showing off cleaner propulsion systems and smarter energy use. The new Star Princess, Star of the Seas, Celebrity Xcel, Norwegian Aqua and MSC World America are the most environmentally advanced leaders of their fleets.

Another welcome improvement was the greater use of outdoor areas, which meant I saw more of the ocean. The best example was Celebrity Xcel's lovely new rooftop restaurant, Bora, and the semi-alfresco Spice Cafe. The resort-style pool deck provided plenty of shade, cabanas, in-water loungers and comfortable couches facing the ocean.

Everyone ramped up the luxury. Oceania Cruises had the most visible glow-up with the glamorous debut of Allura. I also spent two weeks sailing down the WA coast aboard Scenic Eclipse II, a first-time route for this two-year-old discovery yacht with a helicopter and submersible. These ships were my top two for food, too.

Entertainment is moving away from generic productions and more towards recognisable or nostalgic experiences that feel like high-energy parties. My favourite musical was Revolution: A Celebration of Prince on Norwegian Aqua, with special mention of Dirty Dancing in Concert on MSC World America. The best kids' show was Disney Wonder's Marvel Heroes Unite, held on the top deck at night.

My most memorable shore excursions were active, involving nature or wildlife. I loved snowmobiling in the Norwegian Arctic with Havila Voyages, and snorkelling in Palau, guided by the crew of Four Seasons Explorer. Aurora Expeditions' Douglas Mawson made history as the first newbuild to be christened in Sydney Harbour. It sails from Hobart and Dunedin to Antarctica, signalling an exciting era of adventures that conveniently depart from local shores.

Somehow, I didn't do any river cruising, despite 20-plus riverboats launching around the world. Sounds like a plan for 2026.
