Now that your biggest competitor Marriott has joined Starwood and Hyatt in offering their top elites guaranteed 4pm check-out, it's time for Hilton to do the same. I'm tired of having to fight to get a hour late checkout and then the front desk acts like they are doing you a huge favor and you should be on your knees with gratitude.
I would like to see:
1) Guaranteed late checkout for Golds/Diamonds.
2) Breakfast set to a minimum standard. This is where Hyatt shines since their Diamonds get a full breakfast when no lounge is present as mentioned above.
3) Up to 3 rooms credited for points instead of just 2. Also the ability to count multiple rooms as nights towards status like Starwood.
4) Waiving of resort fees/parking for Diamonds.
