I was on the first floor and there were safes with codes. But you can always ask
There are safes on the second floor for all rooms.
Otherwise, for 1st and 3rd floor rooms there is a safe in the central office.
I stayed at Las Colinas for 30 days this winter and nothing
of mine was ever bothered. I think it is a very safe place to stay.
They have 24 hour security every day. It is located in downtown in a safe area. I felt safe there.
Not in the two rooms we stayed in on the first floor.
