Almost all of the hotels, with the exception of the J.W. Marriott and the Ritz-Carlton properties (managed by the same franchisee, YTL Hotels), have low cash rates that may be a better value than points. In August and September 2017 I stayed for nearly two weeks at the Renaissance and a week at the J.W. Marriott with a night in-between at the Majestic.

The Renaissance, which unlike most of the hotels in Kuala Lumpur is managed by Marriott, was just a weird hotel because originally it was two distinct hotels, akin to the Moana Westin Surfrider in Honolulu. Each tower was completely different. Renovations should be almost done by now, if they aren't already finished. I'd be curious to see what they've done with the separate lobbies and the hallways that connect them.

The breakfast at the Renaissance was buffet and low quality. They definitely believe in quantity over quality. I didn't think the buffet breakfast at the J.W. Marriott was any higher quality, though it was more extensive and had more non-Western options. Alcohol at the Renaissance was absurdly priced. I know hotels make their money on booze, but spending more for alcohol than your nightly room rate is a first for me. It was so expensive that in two weeks staying there I only saw 3-4 guests ever drink at the lobby bar, which a couple nights per week had decent entertainment. I felt sorry for the bartenders as they had nothing to do.

I think the renovated rooms at the J.W. Marriott are better, though when I stayed there they didn't renovate the bathroom in the top-floor suite. Housekeeping at the Renaissance had issues. They ran out of towels some days. Other days things weren't restocked. Management seemed to know about this because there were other complaints about the same issues on TripAdvisor.

The executive lounge staff at both properties were equally good. All of the staff after a day or so tried their best to know your name and remember what you like to drink. My glass was never empty. The J.W. Marriott was slightly more generous with alcohol, including self-serve if I remember correctly.

The Renaissance had an awesome pool, supposedly the biggest hotel pool in Malaysia. You could definitely sunbathe there. The J.W. Marriott pool was closed when I was there and guests were redirected to the Ritz-Carlton pool, which was pathetic. Not only doesn't it get any sunshine, but it was pathetically small.

The J.W. Marriott is in the center of action. (The Westin and Ritz-Carlton are neighbors.) The Renaissance is a little more isolated, but it's still an easy walk to the Petronas Towers, which has a big shopping mall and quite a few restaurants. I will say the J.W. Marriott's location was somewhat off-putting because of the street prostitution. I didn't see any of that by the Renaissance whereas it was all over the areas near the J.W. Marriott with the food trucks and street food vendors. It's one thing to see a bawdy houses doing business as a massage parlor. It's something else to be aggressively pitched by a couple dozen women.

Most of the Renaissance guests stayed for 1-2 nights whereas the J.W. Marriott had guests who stayed for a week, for what it's worth.
