I'm going to a conference in San Diego in October and plan to go a few days early to do some sightseeing. I'm looking for the least expensive decent hotel I can find ($150 or less, preferably less) within walking distance of Seaport Village. I did a search for hotels near Seaport Village and came up with lots of results, but I don't know what's where without mapping it all out; I'm not at all familiar with the downtown San Diego area. Some of them appear to be not all that close. My definition of "close to Seaport Village" is within a half-mile walking distance. Suggestions will be most appreciated. Thanks.
