For the OP. I once stayed in
Montgomery Alabama for 5 days. Closest chabad was Mobile, several hours away. For davening, most days, was able to drive to the air force base outside town (in 1997 they had a minyan with orthodox chaplain, not sure the situation today- the business trip revolved around a technology show hosted in part by the base but was not on the base, but at the convention center in downtown) and for food, I was able to bring along vacuum packed food and I stayed at an Extended Stay where all rooms/suites comes with a mini kitchen including a fridge, oven and microwave. I kashered the microwave and if necessary would have kashered the oven, but never needed it. It took several days of planning (the food, and how to warm it/where to stay) and a number of phone calls to make arrangements for davening (finding out if minyanim existed, when and where – chabad of mobile pointed me to the base, and getting the appropriate permission to get onto the base every morning – pre 9/11 it wasn’t easy, I can only imagine what it is like now).
