[QUOTE=Epimetheus]
We are going to STL in a few weeks for a night of fun on the Landing and I would like to find a good relatively inexpensive hotel near the Light Rail. Walking distance is preferable. I don’t know if there are any hotels near the Airport that are like that, but my google skills aren’t that good. 
Any suggestions?

How familiar are you with St. Louis? If your plan is to spend one night there, going just among the airport, lodging, and the Landing, you might look at staying in the Central West End, which in my opinion has better restaurants than the Landing. You could do that without a car – just MetroLink to the Central West End, check in to the hotel, eat, and MetroLink to the Landing for the serious drinking. Unfortunately, your options for lodging in the CWE are limited. There’s the luxury Chase Park Plaza, which probably isn’t what you’re looking for, and which is also a good stroll from the MetroLink stop. But there’s also a Best Western just a few blocks from the train stop (link). I’ve never stayed there, but my brother did once and seemed to think it was OK. It’s next to a major hospital complex, so it’s probably not the quietest place.
You might also look at the hotels around Union Station (link). They’re closer to the Landing, and very convenient to the Union Station restaurants (as well as a quick cab ride to some excellent downtown restaurants), but they look to be in the $150 range. Dunno if that’s in the ballpark for you. The MetroLink stops at Union Station, so they’d be pretty convenient from that perspective.
There’s bound to be something reasonable near the airport, but probably not walkable from the train stop, which is essentially inside the terminal. I suspect the hotels there would have a shuttle, though.
Have you seen this site? It mentions a couple of hotels right at the Landing. Crawling distance, even.
You’re only going to be there for the night? If you have the time and don’t mind cabbing it, you might want to drop by Soulard. I have to admit I’ve never been a huge fan of the Landing. Soulard, IMO, has the best bars in the city. McGurk’s is a holy place. Live Irish music most nights.
Can I come with you? I miss my home town
