Wherever anyone wants to stay in Montgomery is completely up to the individual. Some people like the comforts of national places and some want the quaint little B & B. But what anyone travels to do is get around and look around.
Having a car is of course essential. The airport is about twelve miles out on Highway 80, the infamous Selma Highway, the route taken to Selma in the Montgomery March. So, if you fly in and do not have someone to pick you up, you will need a car. Enough reinforcement of that fact...
Montgomery's good qualities are not just in town though. You have a lot of good things very close, and as a central point for day trips all over the Southeast Montgomery is great. Selma is 50 miles west, Atlanta three hours east, Mobile two hours south, Birmingham one hour north. There are plenty of things to do if the willingness is there to expand horizons a little bit. Also, Montgomery is a lot like larger cities. There are smaller communities all around that are worth taking a lot at with little local cafes, small downtown areas, and landmarks. Prattville (named for the inventor of the cotton gin, Daniel Pratt), Wetumpka (a small town bordering an Indian reservation and full of antique stores), Tallassee (home to one of the best small hotels in the South, the Hotel Talisi), and Tuskegee (home to Tuskegee University and the Tuskegee Airmen) are all less than half an hour from Montgomery. That is not to mention the small farming communities whose landscapes and rolling hills are worth seeing any time of the year. It is easy just drive around in the country and not get bored.
Without going into a tourist guide book description using too many of the same adjectives over and over, I can simply say that driving around the area is worth spending a day or two doing. Do not waste time asking many locals about things worth seeing because so many of us have looked at most of it for so long that it is taken for granted. One thing: take a map and be sure to have AAA because it is hard to get assistance out in the rural areas if you have car trouble, even for a local.
