Quick question about ESTA - flying tomorrow, change of hotel

[xsquared]

The address on my ESTA is no longer the one I am staying at, do I need to reapply for an ESTA or update somehow?

I'm flying out tomorrow, so hoping for a quick answer. Please.

I will go and check the ESTA website now.

You'll be fine. ESTAs are valid for 2 years so if you go back and forth to states you are generally going to be staying somewhere different on each trip.

Thank you. It's just that when I applied, which is back in January, I was booked at another hotel, and then I changed it once my friend had to withdraw. Does it matter that it's a different one even though I applied for it for this trip?

BIL lives in the US and we have also been to Florida and California, often relying on a previous ESTA. You will be fine. They are more interested in the fact that you have booked somewhere to stay than where it is.
Last year we travelled to California and we missed our connection to LA in Amsterdam because Edinburgh Airport had to close its runway so we were diverted to Seattle. That flight was also delayed so we were looking like missing the Seattle to LA flight which would have meant a night in Seattle but it wasn't a problem (in fact our flight to LA was delayed by 5 hours so we made that connection).

Thank you both. Panic over!
