Yes, I like your trip tips - it is pretty good idea to Notify your bank and cell phone company that you're going, so they don't put a hold on your credit.
Of course, it is good to have an Itinerary printed out, to help keep one 'on track'. Especially if you have group members or family with you, so they can KNOW what's coming up .
I feel it's also important (During the Research & Planning phase ) to check on ea. country/destinations for ' Safety concerns' ♦♦ These could be hazards due to mosquitos/health, or merely the fact there are REBELS in the area !
NOTE: As to #restaurants, IF any member of yr Party has special needs (for Gluten-free food items or is Allergic) then Someone better research this ahead of time .
I have an Insightful 'Packing Tips' post that CAN Help people too :
