Thanks for all of the great information. Yes, I do have breakfast included at the Oriental, but if the Peninsula's meal is so much better, I may forfeit the included breakfast once or twice...it was a cheaper room with breakfast than without so I thought I would take it. Also, do you know how the a la carte breakfast is at the Oriental? I requested an email and it is not that highly priced. Lord Jim's sounds really fun - I may have to try that, even though I wasn't planning to.
As for tea, the Oriental sounds really nice. I'm considering doing it when I arrive in BKK as it is in the afternoon. That is a bit wrong that the Pen wouldn't give you free refills. From the teas I've been to (FS LON, Lanesbourough, Claridges, Ritz Madrid), I found that they would all give refills.
Thanks so much, though for the advice.
