The hotel said guests can receive refunds at their point of purchase.
Grande, 25, has had a busy year.
Her song "Thank U, Next" is spending its sixth week at No. 1 on the Billboard Hot 100 chart, she recently earned two Grammy nominations and was named woman of the year by Billboard.
But 2018 also included the end of her engagement to comedian-actor Pete Davidson — who himself has struggled with mental health issues — and the death of her former boyfriend, the rapper Mac Miller.
And in late summer, a bishop at Aretha Franklin's funeral had to apologize for appearing to grope the young singer live on stage.
Meanwhile, May saw the one-year anniversary of a suicide-bomb attack at her concert in Manchester, England, that left 22 dead.
