We did both and start to veer towards s/c nowadays. We also don't do the typical beach/pool holiday anymore.
We had lovely AIs with several restaurants on side and a good bar. But since Covid we found that the prices increased but the food and esp drinks (even soft drinks) offered has come down in quality.
We always venture out and eat out as well, most likely we overpay but found the AI convenience worth it.
For s/c we don't do a big shop and cook each day, we have breakfast there, some snacks in the fridge we can also take with us and drinks. If we have a meal there it will be cold cuts and cheese with fresh bread or - if available - the BBQ.
I always have a dishwasher and washing machine as requirements, if we eat in, DH is sorting out the kitchen before we sit down with drinks. He also does the run for croissants, bread or whatever we want fresh for breakfast in the morning.
Most accomodations now have a cleaner in the price or you can opt for paying extra, so no need to clean outside wiping down a table.
When DH and I are back to childless holidays in 2 years I think we will either do s/c or look for hotel on B&B basis.
