I will be visiting DC in a few weeks. I am in a wheelchair. I have a wheelchair accessible van and so I need a van accessible handicapped parking space. I plan to take the Metro into DC for two days and am trying to find out which area would be the best. I'm looking for a very safe area with ample parking and nice hotels. I have looked inside of DC and have found that parking is going to be a real problem with my van so I am looking for areas outside of DC. I have considered Rockville, Vienna, Springfield but am unsure which offers the most safety, easiest parking, and a pretty nice hotel. Thanks in advance for help.
