i'm sorry to sound uncaring but what the heck were they doing opening tne door in the first place, there are enough notices in hotels and tourist literature saying do not open your door until you have verifiedwho is there. if in doubt ring reception/mantanance/housekeeping to see if they have sent anyone- if not do not open your door. i truly hope they are ok. but it does serve as a reminder to look in, under and around your car at night before you get in, also to look around before you let yourself into your room.
