I have never considered Hilton because I am kind of miffed that they charge $25 per day just to exchange into a Hilton Orlando resort through RCI. I am paying my trading power + $300 exchange fee through RCI + $25 per day. I cannot afford to stay at Hilton with the extra fees for absolutely no perks. Give me transportation to Disney World or Universal, and I am going to consider a stay at a Hilton in Orlando, but until then, I am not ever visiting a Hilton resort in my future.
I am talking Orlando here, and Hilton was my favorite in Orlando (next to Disney), but that love of Hilton dwindled as soon as they started charging those fees. Total turnoff for me.
But the Big Island, I will stay at any Hilton over Wyndham/ Shell resorts (all of which are just average). I love the BI Hilton resorts and don't mind the daily fee + TAT. As long as they keep that daily fee at the current amount, I am okay with it. Kihei is not the area I enjoy for Maui. If I could exchange into the Maui Hilton at some point, I would do it.
I have never been impressed with Diamond properties. The takeover of Diamond by Hilton would not impress me in a timeshare presentation, having stayed in several Diamond resorts over the years. I have never been to a Hilton presentation, but I have been to Diamond, and it was the pushiest I have ever been to, and that is saying a lot. It was Ka'anpali Beach. Total waste of my life, but it was 15 years ago, maybe more.
