No concerns about them breaking from the treatment? I've thought about putting them in luggage to not have to carry, or actually putting one in the luggage and one I carry, and do that with both our suitcases. But I have worried about them breaking because of treatment.
Also, have read of some buying plastic bottles of water in 12 and 24 packs and putting a luggage tag on them and getting them delivered to the room. that would be nice if I thought it would work.
