Thank you!
Well, my stay is in early March, so I have time to decide. Though as mentioned it's getting really hard.
Pros for the Siam Kempinski:
- GHA Titanium
- Better located
- 20% cheaper while higher room category
Pros for WA:
- better breakfast
- newer rooms
- great view
Sadly I only have Gold Status and I heard so much about the noise issues because of the construction site. It really needs to be something special, because it's a birthday present for my mother (showing her Bangkok).
It's a first world problem, but it's really hard to decide which one will have that "wow" factor.
