I think I have 87 days to go

I know it's going to go so fast but I wish it was here already!
LAUNDRY: I plan to do laundry atleast once while we are there on a day we aren't too busy like an AK day. None of us have a lot of shorts and I can see wardrobe changes during breaks due to the heat. I usually have to do laundry atleast once while on any vacation.
TIP QUESTION: We are doing probably 7 table service meals. Any suggestions on how much tip money to bring? We are on the DDP, 2 kids and 2 adults.
WATER DELIVERY: Those of you flying, are you having water delivered and if so who are you getting it from? I don't want to order anything but water and maybe some juiceboxes so I don't know who to go thru. I'm just going to pack a few extra snacks for the kids in our luggage, nothing messy or spillable.
