I don't think so. Usually when a woman is confronted with a situation where she can be up front and blunt, they use strong and specific sentences if they want it.
Her response was ambiguous, unspecific, AND most importantly, the way she worded it, holds no consequence because she can just blow you off this "holiday" at no expense because of the distance between you two and the evasiveness of her statements.
Of course, I also say go for it. I just think she values you at inconsequential, but you have more experience with her than I do. So just take a shot, and if she remains evasive when confronted about it, I don't think she values you like you value her.
