I see several here in past talking about the Hilton Amex card. I travel a lot for work and have moved from Marriott to Hilton for most of my stays.
I talked yesterday to Hilton rep on phone about a stay in Dec 21 and was told I could use my free weekend nights for ANY day of the week in a Standard room at Hilton Aruba no problem... booyahh! I had 4 of these banked up... so used all 4 for a stay + couple more nights with points.
These are only good for STANDARD room which is what I ALWAYS do anyway... we like the Bonaire or Curacao towers and just standard view rooms are fine.
Another Tip... they do specials during the year... one going on right now thru first week July. You can purchase upto 160k points and they double the points you buy. So for $1600 = 160k points + 160k points bonus = 320k points.
Now 5 nights at Hilton is 4 x 80k + 5th night free = 320k points
So you get 5 nights at Hilton for $1600/5 = $320 per night.
This is not free but a good rate since it includes ALL taxes, resort fees other fees... no extra charges...
An I have never seen the days blacked out unless they are just booked up... never had a problem using points here and have done this 10+ times.
So if you like the Hilton you be hard pressed to get a better deal than this I have found.
And as others have said if you have status (Diamond) you get breakfast (cont, or 1/2 price buffet $13) also a discount ~30% on huts/cabaña rentals.
Also it has been noted that you get 10 visits to Priority Club (in Aurba Airport) at not cost. Nice on you flight home...
