Getting a taxi there won't be hard ( you can call through your hotel front desk) or too expensive as it isn't far, I don't know exactly but I would be suprised if it was more than $15 each way. What you might find makes your mind up is the convenience of having a car as opposed to having to worry about how you will get a taxi at the mall. It would also allow you to 1) put shopping in the trunk so you don't have to carry it everywhere with you and 2) allow you to go to other shopping areas if what you wanted wasn't at that particular mall. I'd check howmuch a rental car would cost you going direct to the agents , then bid 50-60% of that cost. You can find Dollar, Budget and Alamo prices all on line.
