Lembeh Resort is absolutely beautiful, but you have to know there is NOTHING to do around the resort except diving. There is a very small spa and yes, there is an excursion to go see those big-eyed monkeys (Tasiers?), but you can't even walk to anything -- it's surrounded by jungle. There is a nice pool but no beach. It seems to me if you want to make it to year eleven (wink), you should find someplace with more activities for your wife. Bali would be IDEAL. Beaches, shopping galore, temples...and fantastic diving, muck and all.
Or if you want a more secluded romantic resort, how about Wakatobi? At least there is a beach, and you can do shore diving or snorkeling with your wife.
Best way to Manado, Bali, the Maldives or anywhere in that part of the world from IAH is with United via NRT to Bangkok or Singapore, then connect thru there. (there is no more Continental)
Are you using an agent? You may want to give Reef and Rainforest a call. The can answer all your questions and probably come up with something perfect.
we just got back from curacao (in fact typing from MIA as i chg planes). its out of the hurricane belt and we didnt see a drop of rain. i've always poo-poo'd caribbean diving but i have to say i was super impressed. lots of amazing shore dives. let me know if yiu need resort recommends, we explored the island .
