We’ve just checked into a haven caravan and it absolutely stinks of cigarette smoke. The curtains, master bedroom and soft furnishings absolutely stink. I’m a non smoker so I’m quite sensitive to it but DH is a smoker and he commented straight away too. There are no other caravans to move to (I’ve asked) and we are 7 hours away from home. What can I do to get the smoke smell out? I’ve got all windows and doors open
