That is a tough one. Yuck! I travel with one of the little scented candles in a tin. Get a good one from a speciatly shop or someplace like Bath & Body Works. The cheap ones won’t do the trick.

lemon!!!

Tell them to smoke cigars after dinner.

Personally, I would go to the manager, (before you even sit on the bed in the room) .. and tell them that you will not accept a room that smells like fish. They have a Master Key, so they can let you in any of the rooms to check out for yourself before you set-up in that room. Assuming the motel/hotel has a 2nd floor, or higher, the fish smell probably won’t make it to the higher rooms. The only thing after that advice is to have the maid come in and spray something in the room to hide the odor. Or, if you go to the same motel/hotel each year with this problem, try a different one. Good Luck !

Air the room out and clean it with an antibacterial cleaner and spray with lysol, clorox, or febreeze and wash your clothes if the scent is in your clothes, request new linen

bread and vinegar. When we have friends over that smoke we put out some fresh white bread and a couple of bowls of white vinegar. Also, baking soda in the carpets helps.

clean it with anything that has a lemon scent to it.
