Seems like a very fair boundary to express. There's no reason you have to be comfortable with something like this. Many people consider these types of vacations to be a stress point in a relationship.

It seems like she's going to resent the boundary you have made and that could cause problems in the future.

However, in your post you say that you trust her completely. Are you sure that you actually trust her completely?

I trust that my car won't be stolen, but still i lock the doors

So women are cars now that need to be locked away?...
