Which and why for a weekend in August? Planning on a couple shows, dinners and museums. All pretty close to both. Time square is a bit more expensive... Points an option... But as RA, I prefer good upgrades to free rooms normally. One night will be paid, to ensure I get my RA renewal this year... Only one IC so far...
No question about it....go with Times Square. The IC Barclay (Lex and 48th) is a dump...one of the worst ICs in the US, imho.
Times Square! You can see my review here, and I've been back twice more and it's just as good. I have noticed the prices have sky rocketed for August and Sept. I was trying to book a Sept. weekend and it is crazy. I did use an award stay here and they still gave me free internet and the same upgrade, but I didn't want to push it and I stayed away from the mini bar.
