I believe its time to move on as I don't anticipate any counter bids on this chain. I had also mentioned Wyndham (NYSE:WYN) as a good alternative in the same post, and investors in WYN since then are up 24% including Thursday's 3.5% move to the upside. If you like the hotel business, I would stay with this name. I still like it here.

Full Disclosure: I do not currently own HLT (sold it Thursday morning) and WYN, but my position can change anytime without notice.
