Best value hotel in Singapore is the Royal Plaza on Scotts.
Just renovated and completely non-smoking hotel.
It is opposite the Hyatt and near the corner of Orchard Rd and Scotts Rd.
Last time I was there, i paid $228 SGD +++, with free brekkie for 2, free drinks in the mini bar (2 beers, 3 soft drinks, 2 bottles of water replenished daily), free wireless.
It's new, clean, great location, and has the best inclusions... what more could you want
