Sites here open in two waves: 143 sites 14 days ahead, released daily, and the rest 2 months ahead, in monthly batches on the 15th.
Opening dates are not known yet: the provider has not published the next season. Sites with a shorter window are released only that close to arrival, at a time the provider does not publish, so they show no availability before then: that does not mean they are sold out.
