Puffy, I have a Acura MDX and I can't lock a trunk so to speak and I understand your concern. I'm not taking your thoughts lightly, but as a person who has used valet parking a ton I have never had anything missing or had a prob. or any sort. The places that have valet parking in effect are'nt like leaving your car with an attentant at the HoJO! These are normally upscale places and the valet's are very well trained. I have not ever had a thing missing or even touched that I could tell, and never a ding or scrath on my cars. I hope you'll reconsider these are very prof. people and will take care of you van and your things.
