A personal friend obtained an OA from London with Nationwide travel insurance 2 years ago when they were at their strictest. I used the same to get a 90 day O visa.
Ive used Agoda for years but they seem to be turning into scammers. Offering cheaper hotel room prices for split bookings but more expensive when you get to check out. Customer service escalates complaints then u hear nothing! Forever emailing discount promo codes but no box to enter them at check out. Agoda Cash used to be good for future bookings but now it expires after a month. This renders it useless for most.
Sorry I forgot your thread is about is about 'marriage'. It doesnt mention for 'Retirement', which is what I am interested in. I will check their website to see if it is available. Thanks.
