Recently stayed at the Virgin Hotel in Vegas (28-30 March '22, part of the Hilton collection). Checked in at 10pm for two nights and was intending to use the two people @ $15 for two nights (total $60) credit to pay for breakfast the following morning. But was told that credit expired at midnight each day - so in reality I had two hours to blow $30, with a new $30 for the following day (expiring at midnight, so not usable for breakfast on the final, check-out morning). Doesn't cost them a penny to allow it to be spread out and combined, so why do this to us? Anyhow, part-paid-for cocktails before bed and a part-paid-for breakfast were the end result. Better than nothing.
