He totally lucked out, right ? - SPOILER !
Newman predicted lava would reach the hotel and that was why they should run, but in fact it never did.
The hotel was hit by two projectiles, which was a fluke. Without that, the people in the hotel would have survived and had a merry old time waiting for the rescue ships while old Blue Eyes would have gotten half of his party killed for no good reason.
Also, a question : where the hell did that giant wave come from (the one that swallowed the town where his mates were, but left the hotel - the one located RIGHT ON THE SHORE - completely untouched) ?
