I got a newsletter from a reporter on this cruise of Oasis, and word is that there are 5000 passengers onboard the Dec 12 sailing of Oasis, so that is actually a very good sign that the numbers are picking up.
Keep in mind this is the slowest few weeks of the entire year when it comes to cruising. After Christmas when wave-season hits, and when a few small glitches get worked out, I am sure Oasis will be selling quite well.
The thing about Oasis is that you have to see it to believe it, otherwise you just can't envision what an awesome (forgive the overused adjective) ship she is. There are just things about the ship where you have to say "Wow" even if it isn't your kind of ship.
