1) Change of categories – Hilton moved from 7 categories to 10 categories and added seasonality. This is very confusion and it is virtually impossible to know the points needed for a redemption without the search tool as some properties have no "low season" and several categories have the same "low season" point level. Date that this took effect : March 28th 2) Elimination of the GLON's – Following Starwoods industry-worse multi-night award discount, Hilton eliminated the GLON's which provided award discounts of up to 25% off for 5+ consecutive award nights booked (20% off only if staying increments of 5 consecutive nights). Date that this took effect : March 28th NOTE: Marriott, which had 2-7 night stay award discounts also went to Starwoods "5th night free" a few years ago so now all the majors either have no multi-night discount or the same up to 20% off only in increments of consecutive 5-night stays. 3) The third wave is here: AXON's will be adjusted for category 5-7 hotels (and category 8-10 added). The good news is that AXON's are still around (first reported on MilePoint and confirmed by ThePointsGuy), although I have not seen anything regarding what the "adjustments" will be. Date that the adjustments will take effect: June 15th. For those hotels that are still Category 5-7 and you may be staying during during Peak season it may make sense to proactively book AXON's.
