They said it's biodegradable naman daw and it will be held indoors.from their website they've just decided to cancel the balloon drop to respect DENR's request. Boring lang para sa kin if sa Pinas ka at manonood ka lang mg balloon drop. Mas gusto ko pang magpaputok. LOLSpeaking of Okada, they have one of the ugliest interior design for a hotel. Yung lobby & foyer nila mukhang may debut because of the ubiquity of pink drapes. And their room as well. It lacks the touch of opulence. The only good thing in their rooms is the jacuzzi. Mas ok pa rin ang loob ng Solaire.
