Or cheesy like the heart-shaped jacuzzi in American Inn off of NW Hwy. Which, don't ever go there!  

I do know that some of the 3.5 to 4 star hotels have romance packages, and you're more likely to find a jacuzzi for two. Nonetheless, when I'm traveling, any hotel that has a nice big bathtub and hot water is just begging for me to take a soak.  

Lastly, you could always go to King's Spa or Castle Spa and relax in one of their sauna tubs for $35.  

Nonetheless, welcome to Dallas!

I am not sure if you have made it here and have gone. But I used to use a Nice hotel when i first got started in Garland that is affordable and they have 2 jacuzzi rooms.  They are nice because I have used them for meetings and a photoshoot
