Seriously though it depends on the destination. With sun destinations I always overpack and find I use a third of what I bring. So I started doing carryons only. Most places you go will have sunscreen you can buy or shampoo you can buy so it doesn’t make sense to pay for check in.
One thing to keep in mind is you’re generally allowed a carry on and a personal item. So make your personal item count. I normally bring a duffel bag and a regular size knapsack. If you really need to bring liquids go to your local dollar store and buy a few of those containers under 75ml. You’ll be fine.
