We still have a valid ESTA from our last trip to US in 2009. ESTA website states it is valied until 29th August, 2011 and we arrive on 21st June this year. So i assume this is valid and there is no need for us to go through process for new ESTA, right? Do I need to update address details as we are not staying at same hotel as last time?
Also, we will be travelling with our adopted daughter who travels on a passport requiring a visa. Am I right in my thinking that she will not need an ESTA as this is for visa waiver countries only?
