Sorry to thread hijack, but I'm curious....
We're planning on visiting the US for the first time as a family. Three children and one adult (me) with dual nationality (US/Brit), husband with just British.
We weren't planning on taking cash as it's easier to use credit cards etc these days. Will I need to take a print out of my credit limit?
Would we need any other documents, we have return tickets and hotel tickets etc. Obviously he has done ESTA already.
