30 million is peanuts for relief work. And most or all of it was donated (coerced) from fellow believers. I have never heard of any displaced family being put up in a hotel, just in the homes of some better off witness.
Don't forget to make your check out to world wide work, not a specific disaster. Last charitable donations I made were to give money to a needy couple directly, and I took some of the funds from what would have been in the contribution box otherwise. Knew of the good they had done in the past so I figured it was only the pay it forward type of thing.
I never contribute to anything but the local hall; they send enough on to the top from the cong account.
