LOL.  Given her own choice, Jessy would likely kindly volunteer herself to room with Tami, assuming that she knew her previously, and that Tami of course agreed.  Their interests wouldn't likely lead them in the same group very often.  I suppose it partially depends on the level of familiarity between the group, and the reason for the trip.  If it is Tasha's plan to bring several of her various friends together, or if the group are already good friends and it is just a nice relaxing trip.  This is of course up to the vote of the entirety I would believe.
