I guess it depends on where you travel and when. Went to Key West last September and used airfare credit to fly to Miami. Found this trip to be more expensive than a cruise by a long shot. Hotel (and this was off season) was $$ and we chose a mid price hotel not a resort. Add in food, drinks, and a few excursions and our 4 day trip was as much or more than an OV cabin on a cruise.
We sailed on Princess in Feb and it was cheaper than Celebrity for a wonderful mini suite. Also, specialty dining was cheaper and excellent quality. We are booked again on Princess for November, again in a mini suite. We loved Princess but are coming back to Celebrity for October 2023 in Aqua mainly because we are elite, have many many credit card points, and miss Aqua. This 8 day trip is more expensive than our November Princess. At this point now, we will be not loyal to Celebrity or Princess but make choices based on itinerary and price
