We have 6 nights at the Conrad in Samui followed by 6 nights at the Renaissance in Phuket. If the Thai flight was leaps and bounds better I would cut the Phuket side down to 5 nights. I actually like the new United F seats. Wish the Thai'd updated flights were avail on the way back (my flight out in F is on an A320 from MUC which I believe is/will be updated) May keep looking for BKK-FRA or BKK-MUC.

Thanks for your help.
