Hi Stacy, I'm doing Tiger Airways and staying with a friend
Without going into details, here's my itinerary & ideas:
1. Tailoring Clothes - Sukhumvit Area
2. Massage - HealthLand
3. Food - (Seafood):Somboon or Baan Klang Nam, (all sorts):Covent Road area, (Italian):Silom
4. Clubbing - (Trance)RCA or (Hiphop)Escudo
5. Market Shopping - Chatuchak, Chinatown, Pahurat, Sampeng, Suan Lum, Patpong
6. Indoor Shopping - MBK, Siam (Paragon, Square, Discovery Centre), Central Chidlom
7. Chill out - BKK State Tower
Hope this helps
Erm, we'd probably not be able to go to everything here - will probably play by ear (and by pocket ($$) heh!
