Hyatt appears to be quietly running a promo for Andaz properties which means that stays between 1 July and 31 August (based on check-out) count double for earning World of Hyatt status.

The page which references this offer is here.

The T&C’s say:

You must be a member of World of Hyatt to participate in promotion. To join World of Hyatt, visit worldofhyatt.com. All eligible nights under this promotion must have a checkout date from July 1, 2018 through August 31, 2018 (“Promotion Period”). Each eligible night completed at Andaz properties during the Promotion Period will count as two (2) nights, instead of one (1), for the purpose of tier qualification for Discoverist, Explorist and Globalist status. The extra night credit will also count towards benefits and awards that explicitly require a certain number of qualifying nights. For the purpose of this promotion, an “Eligible Night” is defined as any night where a member is paying an Eligible Rate or redeems a free night award for at least one night of their stay. Only the room occupied by the Member will count toward this promotion. You must provide your World of Hyatt membership number at the time of check-in for each stay. Promotional nights earned for stays completed with a checkout date between July 1 and July 31 will be deposited in your account the first week in August and promotional nights earned for stays completed with a checkout date between August 1 and August 31 will be deposited in your account the first week in September. All nights associated with this promotion will be posted to your World of Hyatt account (My Past Activity section). Promotion not valid with other offers, promotions or discounts and is non-transferable.

No registration appears to be needed from what I can see.
