I just responded to this one this morning and I think there are a few other suggestions there: http://community.thebump.com/cs/ks/forums/thread/10297091.aspx
I went to Sugar House in Old Town on Monday and had a fanstastic massage. It was $90 for 50 minutes and worth every penny. They have the belly pillow which allows you to lay on your stomach. I went to Massage Envy in Potomac Yard and frankly it sucked. I had to lay on my side which I didn't like as much and they kept making me change positions so I had a hard time relaxing.
