Going to Aruba with my 3.5 yr old and DS2 will be 19 months (and a monster Chat Icon )

We've been going every year, but my 1 yr old can't sit still.

Here's what I'm thinking. Let me know what else..

For the plane. Backpack of...
Diapers + overnight
Extra clothes
Wipes
Purell wipes
Crayons/coloring book
Extra toys
Videos
Sippy cups and water
Snacks
Of course wallet, passports, tix, etc
Extra little bags for garbage

To pack...
Bathing suits and rash guards
Shorts, tanks
Water shoes and sandals
More wipes and diapers
Sippy cups
sunscreen
Hats, sunglasses
Swimmies
Sweatshirt in case
One or two nice outfits for them, but we really don't take them out and usually stay on the beach. My IL's come too so when they watch them some nights DH and I go out
Lots of ziplocks
Beach bag
Lotions, comb, travel soap and shampoo
Medical kits w neosporin, Motrin, bandaide, aquaphor
A few sand toys, but the Marriott usually has a bin for kids
life jackets
This is for them. Am I missing something? I will pack extra toys for the room, but we don't stay in there that much. Just for at night.

We have a timeshare and go food shopping there.
We also uses their crib for the baby and my 3.5 yr old will use a extra bed we make on the floor.
Thanksz,
