We are headed to Texas from Maine next week. Our first overnight stop is Arlington, VA to visit the national monuments. Going to spend a couple nights there. Then, two nights in Nashville...also stopping in Memphis. From Memphis we will be going through Arkansas & stopping at Hot Springs National Park. From there we will be headed to Texas, Stopping in Dallas for a couple nights. A majority of our overnights will be in hotels, but a few nights we will be sleeping in our SUV. Any tips on sleeping in a SUV and hotel hopping? What other roadtrip tips do you fellow gypsies have?? What do you you do to save money on the road?? Recommendations for things to do/restaurants in Arlington, VA/Washington DC, Nashville & Memphis, and Dallas TX?! Thanks so much!!
