I will arrive in Lagos for a 20 hour transit en route to Douala.
However, Nigeria requires me to get a letter of invitation to enter the country - even for 20 hours.

The hotel I have been booked in won't write me a letter.

Whats the best way for me to get a LOI - can someone please help?

Thanks
Daniel from Australia

Your airline or travel agent should do that. That's the global practice.

We are now Being careful who enter our country.

Thank you, understandably so.

However, this is two separate bookings - they are not interlined, hence my trouble obtaining a visa directly from the airline.
