Thanks I already made the suggestion.
Certainly should be cleaner but personally I don’t go on vacation to do bus mold inspections, or any other kind of inspections. Hopefully the home or hotel is better ,mold free but doubt it. Sxm is a fairly damp climate and mold happens.
Can't say I go on vaca doing the same either. Just so happened that we spent 10 on that bus and I looked up. It was pretty egregious.
As someone suggested, masks would definitely be advisable on the bus. Inhaling fungal spores can present a greater challenge on our immune systems than respiratory viruses.
