I'm just wondering if there is a Walgreens, CVS, or something within walking distance from the onsite hotels. If there is...how far is it and how do I get there on foot?
There is a Walgreens across the street on Kirkman. I wouldn't walk there since you have to cross 8 lanes of traffic and it would be a good 30 minute walk.
Provided you know how to put one foot in front of the other it will not be a problem. There is a traffic light that gives you plenty of time to cross. I have done it many times. It is no different than crossing any street with a traffic light.
