I already don’t use airbnb but booking.com? Almost all holidays. That would be really hard to replace. Does anyone have any alternatives (other than directly calling the hotels obv)? I guess one could atleast minimally search from booking.com and then first check if the hotels you are interested in have their own online reservation systems. But it will probably be much less guaranteed than booking.com and one could easily end up with a holiday ruined and a mere apology for “making a reservation mistake”
