Walk in weddings abroad

[teabag20048]

I have read you can walk in and get married in Florida, presumably Las Vegas too anyone know anywhere abroad you can do this?
We were thinking of a registry office here but cannot find anywhere to do something nice afterwards.

I’d also be interested to know... preferably not US!

Vegas.
You have to register with the Clark county office, you can't just walk in to a chapel and get married.
But the wedding chapels would put you in a taxi/limo to go and do this and bring you back to get married.
You obviously need to provide ID etc to registers.
