I know that this is an odd question, but can you have more than one vehicle down there, i'd like to have my truck and my motorcycle (errands/commuting) while I'm doing my CP
I can't say that I've ever known somebody that had two vehicles down there at once, but I really don't see why that would be a problem. Just make sure to get two parking passes I suppose.
I drove my car down and near the end of the program I bought a motorcycle. They pulled my records and it showed I already had one vehicle there and it might be a problem, but in the end they issued me a sticker for my bike as well.
