The critical moment is not the hotel. It is the twenty minutes after you get home with the case, and almost everybody gets it wrong in the same way: they put it on the bed.
A suitcase never goes on a bed, and never goes in a bedroom until it has been dealt with.
That is the whole of it. Unpacking onto a bed is the single commonest way a bed bug that has travelled in a case gets from the case into a mattress seam, and it takes about four seconds.
Do the washing before you go to bed. A bag of holiday clothes left in the hall for a week is the same problem as a laundry basket on a landing, with the addition that it has just come from somewhere else.
Five places, and it takes about three minutes with a torch.
A hard-shell case with a smooth lining offers considerably less than a soft fabric one with external pockets. That is not a reason to buy a new case, but it is worth knowing which sort you are checking.
Storing a case inside a large sealed bag adds a useful layer, particularly for a case that goes months between trips.
If you found evidence in the room you stayed in, or somebody has since told you the property had a problem, treat the case as infested rather than as suspect.
A case that has been in a bedroom is a bedroom question. If it went on the bed or under it before you thought about any of this, the case is no longer the issue - check the mattress piping at the head end and go from there.

Somewhere hard-floored - a hall, utility room, garage or bathroom. Not on a bed and not on carpet. Unpacking onto a bed is the commonest way a travelling insect reaches a mattress.
Yes, if they were in the case. Everything that travelled gets a hot wash and a full hot tumble dry - the dryer is the stage doing most of the work.
Five places with a torch: the lining edges, the zip channels, the internal pockets and their seams, the wheel and handle housings, and under any retaining straps. About three minutes.
Treatment starts from £220 for the first room. Tell us how many rooms people are sleeping in, what you have found — live insects, dark spotting, cast skins — and how long it has been going on, and we will come back to you.
