Definitely recommend Eka as a good viable alternative to Ole Sereni. A friend stayed there recently for bed/breakfast & hotel transfers for US$180. The other nearby hotel (not really so recommended) is Panari - but all of which are within 1km of each other, and only a 10 min ride to the airport. Opening soon is a hotel owned by Carnivore Restuarant, next to Wilson airport, and a short ride from JKA - will be interesting to see what its like....
