The Ritz Carlton Millenia Singapore is a beautiful hotel and the staff is extremely helpful ... the rooms are spacious and the bathrooms are FANTASTIC! You can soak in the tub and have the most amazing views of Singapore while doing it. The workout facility is fantastic as well, the pool is decent.
The only problem I've had at the Ritz in Singapore (having stayed there multiple times) ... is that I got food poisoning from the buffet! And so did my coworker on the same trip! I'm not exactly sure which food it was (the doctor said it was uncooked chicken or fish) but it was the worst food poisoning I've ever gotten. After returning to the states and being diagnosed, we called the hotel and they said they hadn't gotten any other complaints but we are 100% sure we got it at the Ritz. The last few days of our trip - we ONLY ate at that restaurant (we were there for work and swamped) - so it was definitely from there. They comped us one meal for our troubles (we were surprised they didn't offer more - but if they hadn't received otehr complaints at that point - maybe they didn't believe us).
Regardless of the food poisoning, the hotel really is quite lovely and I've stayed there again since with no problems. I'd just be a little skeptical of the buffet
