Majestic Suites willbe the best..Nice hotel and if you take a girl or girls from Nana, you'll be in your room less then 5 min.
From there you can take the skytrain to Ekemai Bus station only 10-15 min...That is if you haven't got a heavy luggage...There is a aircon. bus service to Pattaya every 30min. and it takes the allmost the same time to Pattaya. 105 bt I think..
