Not sure where to find a close up map but the hotels along hotel boulevard are all within walking distance of DTD i.e these:

You can also walk from the crossroads area of LBV but it takes longer as this is the far end of the hotel "strip" (see the other recent thread on where to stay in LBV) about 10 -15 mins I would say.
Closest hotels to DTD are Hilton, Grosvenor & Wyndham Palace all about 5 - 10 mins walk to DTD - the Marketplace end - you still have another 10 - 15 min walk from there to get to Westside etc.
