I like
CAO Eileen's Dream (generally requires some significant drying time but tasty for an Aro, and it does have a pleasing room note, slightly chocolatey with a whiskey undertone and similar flavors)
trout stream (A cavendish blend with a room note and flavor both reminiscent of a vanilla or caramel, as a rule this has not required much if any drying time for me)
Lane Limited 1q(again this has a pleasing room note similar to vanilla or possibly sugar cookies. it is a lighter flavor than the other two and is still a good tasting cavendish blend)
Captain Black Gold(this is one of the first OTCs I have found that I actually enjoy the smoke, it is somewhere between 1q and trout stream, but with a slightly "darker" flavor, again the room note has that caramel or vanilla scent)
and finally
Petersons Irish oak(a lovely blend with just enough perique to lend it a super mild english flavor. This one has a smooth room note that is not easy to identify but I've never gotten a complaint from it
The links I've provided are all to the P&C pages and do provide some reviews of the noted tobaccos. You may want to sit down and go through some reviews with her at some point in order to find something that the room note description sounds good to her
