Great thread. I am scheduled to London for work in late October (will use a Hyatt nearest our office) and to Tokyo for work in early December (Hyatt Centric Ginza). But I think it's 50% likelihood they will be rescheduled - there are still a lot of unknowns. (Will company travel be allowed, and/or will US citizens be allowed in the UK or Japan?)
Hawaii is reserved for Christmas (Hyatt Regency Waikiki Towers) - that feels more likely to happen given it is domestic travel, and I don't foresee any scenario where Hawaii is not mostly reopened then, optimally with no in room quarantine.
Aspiration wise, I hope to go to Oman in the first part of next year, staying at the Alila Jabal Akhdar and also the Muscat Kempinski. Oman looks utterly fascinating.
