Ugandan Visa for US Citizen - In Advance or at Airport?

I'm a US citizen and will be traveling in Uganda for one week. Is it worth obtaining a Visa in advance, or is this relatively easy to do at the Entebbe airport upon arrival? I will be flying in from Nairobi. Any advice on this would be appreciated!

It is possible to obtain the Uganda visa on arrival. depending on what you are going to do in Uganda, your are to pay $50 for your visa.

Very easy, i agree with the above people

Easy peasy! You will have no problem at the airport
