Avid HiltonHonors member - super dissapointed.
I booked 3 nights during Labor Day at this hotel and upon arrival realized this was unlike all the other Hiltons I've stayed at. Upon checking-in we were told our King bayfront view room was no longer available and that we were being moved into a double queen room for our stay. Considering I payed extra points for the king and specified in the request that I wanted 1 bed, not 2, this still happened. After pushing back for nearly 20 minutes, we were told they'd try to find a king room for us the other 2 nights, but no guarantees. That night we realized we had forgotten toothpaste and buzzed guest services with the request; it never came. The following day we did the same along with the request for a razor. 2 hours later we called to remind them of our request. 30 minutes later it arrived. 
We were given free breakfast buffet vouchers, which we realized everyone in the hotel had when we went downstairs for line. It's funny how they can take away amenities and give them back as unique gifts that are actually ubiquitous.
If this is any consolation, I was told that the hotel originally wasn't a Hilton but Hilton purchased them "because they were so good". Nonetheless, I've stayed at Hiltons in Napa, Cabo San Lucas, and Los Angeles that have never been this bad. Stay somewhere else if you can while visiting San Diego.
