Although there are many possible ailments that can be treated with the above remedies, I recommend adding some antibacterial ointment such as Neosporin to your first aid kit. I'm not the most ambitious when it comes to my hair, especially if I'm travelling with kids. Amazon has lots of cute elastics & pins you can use for fun ponytails and updos that keep your hair down.
For Vegas, I recommend packing two outfits each day: one for the day and one for the evening. This is my general rule. Even if you don't plan on dressing up for an evening activity, you will need to change clothes as the clothing you wore throughout the day may be sweaty or smoky.
These little devices are great for reducing the number of surfaces you touch. They can be used to open doors or to avoid touching surfaces. Make sure to clean them. It's difficult to find a clear answer because there are so many opinions about packing for Vegas.

It is tiny, about the size of a tube lipstick. This makes it very portable. You can also use it to charge your item while it is safely stored in your bag. While you might find some charging stations in casinos or at events, they are expensive. It is worth investing in your own portable charger.
A cute, casual outfit that you can wear to the nightclubs includes a bodysuit, black jeans, and a pair or heels. If you are not celebrating a special occasion, I wear this outfit to Las Vegas nightclubs. It is easy to dress up or down a body suit. You can wear it with jeans for daytime sightseeing, black jeans at nightclubs, or a skirt for dinner. It doesn't matter if you travel in winter or summer, so make sure to get one with a shorter or longer sleeves. I love a bodysuit as my favorite travel outfit. It doesn't matter if it is summer or winter; you can get one with either a short- or long-sleeve.
Two outfits are enough for Vegas. I pack one outfit for each day for my husband, and one for me. Even if it's not the evening, you'll want to change clothes. It's possible that your day's outfit might have been sweaty and smoky. Check out seasonal activities while looking for Las Vegas travel offers. Fall and winter are the best times to attend crowd-pleasing events such the Super Bowl, NASCAR Race, and Rodeo.
It is also small (about the size of a lipstick tube), so it can be carried around with you and even charged while you're out. Although you may find recharging stations at casinos or other event venues, it can be quite expensive to use. So, having your own charger is a great idea.
