My reference was for KUL in general, and not in relation to the the specific area where the Grand Hyatt is in. It is also a past warning, and nothing eventuated from that as well. If anything, the GH and Shangri-La are only half a mile apart.

I should also clarify and stress that there is currently NO official travel alerts or warnings for KUL from the UK, US, or Australia. Personally speaking, I do not feel the need to reconsider travel to any parts of KUL due to safety/terrorism/whats-nots.

While I've never planned to be at the Grand Hyatt, I'll just be a few hundred yards away in the direction of the shopping malls and do not feel unsafe with the currently available information.
