Hi there,
Thank you for your email. 🙂
Sorry, I could only refer you to Ellenborough Market to check on this deal. Their contact details is as below :
Tel : 62391848 / 62391847
Email : emc.reservations@swissotel.com
But from my experience on several hotel buffet, they usually have a cap amount of pax. e.g. Straits Cafe at Hotel Rendezvous, they allow diners to use multiple credit cards to make payment for one party in order to enjoy the max benefits of the deal.
Hope this helps 🙂
Cheers
Dawn
