2. All the children (and adults) need a hat with a brim. I cannot stress this enough. It really keeps you cool. It is very hot and everyone needs one. A baseball cap is ok, but one with a full brim is better to prevent sunburned necks.
3. Bring your sunscreen favorites (spray, lotion, etc) reapply throughout the day. You will need to use insect repellent as well. We have lots here but if you have a favorite brand that you use on kids at home, you should bring it. It is most useful in desert areas.
4. Bring water shoes for the City of David tunnels, rafting and Ein Gedi. No flip flops
5. Buy water for your apartment and Air B and B. Make sure people start drinking water BEFORE you leave for the day. Buy some of the hand water bottle cooling things. They hold a liter or liter and a half of water. You can refrigerate your water the night before and place them in those things to keep chilled.
6. Make sure you know all your passwords for your ATM cards and call all credit card companies and tell them you are going to Israel, so charges are not denied.
7. You should have a good data plan on at least one cell phone because if you are driving in a rental car you will definitely need to be able to access WAZE and What's App.
8. Buy a driving map of Israel. The rental car companies are not so good about giving one. It is great for the kids to see where they are going and the outline of the country as you guys drive around.
9. Shop for snacks and bring daily. Best to have at least one or two persons carry a regular backpack. That way, it will fit water, snacks and souvenirs if you buy
10. Take good pictures of the rental car before you head out.
11. Bring medication for everyone and if needed, bring a prescription from your doctor if you run out. Bring your favorite over the counter meds in small quantities. You need a prescription here for neosporin!
12. Buy travel insurance and also check your insurance policies to see what is covered overseas.
