crissyp,
I just got back from the 2/19-2/22 Wonder. I did bring Lysol & I am glad I did. I used it to spray the necks of the life vests in the stateroom. You have to go to a life boat drill - wearing the life vests - just before the cruise leaves port. The life vests are only used for the drills (at least so far - fingers crossed!), but obviously lots of people have worn the vests. Waiting on deck for our drill, we were in the direct sun & we were sweating. The lifevests (ours anyway) were soiled around the neck & stinky. I guess others before us had sweated during the drill, too. So, to make a long story short, bring Lysol. You can use it to spray the lifevests, or to spray the toilet or door knobs if lots of people are sick on board, or just to "freshen up" the air in the toilet area if someone stinks it up. We got a small can of Lysol at our local Mobil on the Run (grocery store at gas station). That was the only place I could find a small lysol. They're giant cans everywhere else!
Have a great cruise!
