You expect to have about 1000 attendees over 3 days. The hotel has only 290 rooms so you hope to reserve all or most of them for your attendees until a little before the event. It would be best to block them until two weeks before the event, but really, the attendees should plan and reserve four to eight weeks in advance. The retail cost of a hotel room is $250 US (about 2000 HKD), and this is certainly too expensive for most of your attendees, so you feel it is necessary to lower the price to at most $190 per night. You could guarantee some of those rooms will be filled, but you are nervous about guaranteeing all of them, of course. Breakfasts at the hotel are quite expensive in addition to the hotel room, so you would like to secure free breakfasts for your ten staff members and a 2050% discount for all conference attendees. You know that the hotel usually offers free access to the swimming pool, but you have heard the pool is small and crowded, so it might not really be useful for your attendees. The fitness room, however, is supposed to be quite good, but is not free.
