Have friends going on a honeymoon to South Africa. Wanted to book reservations at the Tasting Room (in Le Quartier Francais Hotel where they were staying) near Cape Town. The reservations only open 30 days in advance and book up quickly on Sat. nights. Called a few days in advance of 30 days, Concierge knew exactly what was up, said they would adjust for time difference and call (international calling) and make the reservation for our friends (used my Plat card to guarantee res), and even handled international faxing of the reservation guarantee.
Helped out b/c they called at 3am EST to make res, plus I didn't have to make int'l call.
