Thanks c-w-s. The Lost Property's website now says "accepting reservations for July 18, 2022 and beyond". (My June booking still shows as valid, not sure if it will be cancelled at some point).
I haven't been able to reach the property on the phone. I did try sending an email to
[email protected] but it bounced back. Would Hilton Honors be willing to rebook us into another property nearby or simply refund the points? Thanks.
