I live in San Antonio and have been to Dallas a few times to see Dr. Lam. Here are some tips you might find helpful.
Hyatt Place: This place was nice. The room set up is cool because it has a little partition between the sleeping area and the living area. They also have a tv in the room that integrates with your mp3 player or portable dvd player which is great if you are traveling with children. If I was traveling to Dallas alone and was only staying one night (and didn't want to spend a lot of money), I'd probably stay here again.
Westin Stonebriar: Beautiful hotel! Superior service. Lots of amenities including valet parking (for a fee), nice restaurant, bar, gift shop and coffee shop. We preferred this hotel over Hyatt Place because it offers room service and is really more of a full service hotel. They even gave my 3 year old a cute little bag with games and a hat when we checked in! Prices are higher but worth it. Next time my husband is bringing his golf clubs because they have a golf course right behind the hotel!
Another travel tip when going to see Dr. Lam is be prepared for the toll roads if you are driving. It's a good idea to have some change in your car so you don't have to look for it while driving. I think most tolls were $1.00 but you can't use dollar bills so have some quarters ready in your side door pocket!
We enjoyed both the Stonebriar and Willow Bend Malls. We were impressed how the Stonebriar mall has "family bathrooms" which is always a plus. They both also have fun little indoor play areas for kids. My husband would just take the kids shopping while I was at my appointment and then I'd call him when I was done. Very handy to have so many nice malls close to Dr. Lam's office! Next time I think my husband wants to have a massage at the spa in Dr. Lam's building.
If I think of anything else, I'll be sure to post here.
