The Megabus is opening a location in my city and while it would take 12 hours and a bus change I can go to DC and back with my 10 year old for only $10.50. this really has my attention because I'd love to show her the city. I'm thinking 3 days in DC and we lose 2 for travel so I need 4 nights in a hotel. I need a place that is safe and in the center since we would have no car. I'm just wondering if anyone knows a time period thats best to check during July and august? I'm not tied to any dates just that time frame. I need to keep costs down as much as possible because m husband is already upset and thinks its unsafe for me to go alone with our daughter to DC. thanks for any suggestions.
