Ditto what everyone has said.
$100s great at most restaurants, $50s will work on Orient and we bring A LOT of $1 for tipping.
Neutrogena is great because of the 3 oz sizes. I also pick up a few of the 1 oz just in case and their face stick(which I put in my make-up bag). We do carry on only and haven't had a problem of running out. Don't know if they carry on the island.
