This advice is spot on!
Skip the overpriced Novotel at the airport and find a nice/reasonable hotel downtown/Sukhumvit Rd.
As stated by previous poster, early in morning a taxi to BKK will take you 45 min max and should be around THB 250-300 + toll way fees (by taxi meter) from Sukhumvit (or get a flat rate from the driver of THB 400 a/i when you get in the cab).
