Wow, this is going deep into the mists of my memory. I think it was the (former) Westin in Cebu, Philippines in the late 1980s or the (former) Sheraton Manila in the mid 1990s. I'm just not certain whether either Westin or Sheraton were part of Starwood at those times.

Anyway, nice to see that Starwood is returning to the Philippines over the next few years.
