We were signed up for the 2024 ATW aboard Insignia - cancellation fee was $500 per person. Maybe a world cruise is more $ to cancel. Food and service appear to be very similar. Don’t think I would rank one higher than the other. We just completed a crossing from Lisbon to Miami aboard the new SB exploration ship, the Pursuit. If you want to walk with the penguins, the Pursuit and the Venture offer amazing adventures to Antartica, the Falklands and South Georgia. Passengers - 254!!
