In times gone by, Easter would come and Easter would go. There would be a hiatus, as everyone knew there would be. The later the Easter, however, and the more the hotels would open; they could live with a couple of quiet weeks ahead of the starting-gun being fired on the first of May for the official start of the season (as is generally accepted). An early Easter, and there was greater reluctance to open; four weeks are longer than two.
Over a period of years until the doors were slammed shut in 2020, there had been a greater blurring of the season’s start. The first of May seemed to apply less and less, though it depended on resort or even area of a resort. Nevertheless, Easter had genuinely come to herald the start of the season, a happy state of affairs assisted in no small part by active tourism (cycling, hiking) and for a time by the “borrowing” of holidaymakers from destinations affected by terrorism.
