My DS has gotten it several times from daycare.
For my DS, the doctor gave the really strong eye drops that are 3 times a day (though he said to be safe to continue to treat him until 3 days AFTER symptoms have cleared up. So ended up treating him 6 days). Great for a 2 year old. One thing, you can ask for these to be called in proactively for you and anyone else that might not have caught it yet. If you have a good relationship with your doctor and explained you're heading on vacation, I'm sure they'd call them in "just in case." My doctor actually gave us a prescription to keep on hand so that we could use it before bringing him in if he caught it again.
Make sure you are religious about handwashing for EVERYONE in the house. Clean off all the surfaces you'd normally touch often (door handles, light switches, toilet handle). Every person who is already infected needs to use their OWN hand towel to dry their hands. Do not share a hand towel.
If the pink eye is only in one eye, try to encourage that person to not touch the good eye and to sleep so that any goo drains away from the non-infected eye. That might keep it from spreading to both eyes.
Remember, even after you stop having symptoms, you still can have pink eye and are still contagious. (which is why it is so easy to spread around daycares. Parents will treat the child until it's not visible, send them back and then they spread to another child.) Our doctor said to continue treating until 3 days after no symptoms appear.
Good luck!
