Easiest food and minyan will be Scottsdale. Plenty of VRBO near shul for rent, though its possible that for winter break, you may be a bit late to the party. Dallas, has a hotel within the eiruv, Cooper Hotel, that we stayed at, that is within a few minutes of 2 shuls. Can pick up takeout in a couple of the supermarkets. Didn't stay in New Orleans for shabbos, so didn't look into walking distance to shul places to stay, but can get food from Kosher Cajun.
