There are 5 properties in Oahu with 4 located within the Hilton Hawaiian Village (Lagoon Tower, Kalia Tower, Grand Waikikian Tower and Grand Islander Tower) and one near the main shopping strip (Hokulani). Three are only available 9 months out (Lagoon, Kalia and Grand Waikikian). The other two (Grand Islander and Hokulani) become available 6 months out. Since Lagoon and Kalia towers cost less points (under the original point structure), they're normally grabbed first.
How did you manage to get three rooms in August using bonus points (which are non-changeable)?

Did you book the higher point Grand Waikikian rooms once all dates were available to book online or did you walk your reservations using your Club Points then release and rebook using bonus points for all three rooms?
