HP is fixed weeks so no Platinum. Platinum at GO is week 24-34 and at BB & SW is 22-34. It can be a good deal depending on the final price and unit type. HP has 4 types of units (A, B, C & D). A & B are the tops and D are the pits though given the way II works, they all trade the same.
HP was developed by the Burns Corp and bought by Marriott in the 80's around the same time they bought Monarch. There are still quite a few of the old owners around and they are not that thrilled with Marriott as a group. Not that they're upset, just that they are indifferent, much like many of the owners in Vail were.
For a HH stay, there are better choices IMO. GO gold might be a great choice to use as it goes through later in June. SW and BB gardenview are great resorts to use and trade both. HP compared to
DVC HH is in a better location from a view standpoint but a little worse from a standpoint of walking to activities/dining. If you can go during early to mid June you might also consider a better choice from a trading standpoint and try to trade in from time to time.
IMO, HP used to be the best trading value for a Marriott ownership but I no longer feel that is true for several reasons including the fees have gone up, it's not a lockoff and I suspect it won't be a Marriott too many more years. I have owned at HP and have stayed there twice as well as having stayed at DVC. There are a number of inaccuracies in the add. HP sleeps 6, not 8, there are no 980 sq ft units, there is no unit 3 and the picture is of Sunset Pointe not HP. OTOH, I have bought from this lister and while we are not finished with closing, the communication and follow up has been good on his part. I am not nearly as happy with the closing company though. If you find out more specifics or have questions email me and I can likely help you figure out if this is a unit you might truly want vs a lessor unit you may not.
