ooops... Pinnacle Hotel 8/10 miles from Silom Road?????? No no no, it's really not that far!!!! It's much less, would be about 15-20 minutes walking time to Silom Road (Dusit Thani).

Hope, you're not speaking of one of the other two Pinnacle Hotels in Bangkok (Pinnacle Inn and Pinnacle Sukhumvit?)! Be sure, it's Pinnacle Hotel Lumpinee!!
