Just got back yesterday - we were really surprised at how fantastic the Cruise was! We thought only boring old farts went on Cruises - well, yes they do but lots of other fun, young people do too!
The weather was cloudy/rainy for the first few days but then the sun came out and it was all so perfect. We had a cabin right at the pointy end of the ship on Deck 2 - we actually loved being able to really feel like we were on a boat (think crashing waves, portholes, lots of motion from the ocean and being able to feel like the anchor was coming down right through the centre of our cabin!), even though I got seasick the first night, some free Bonine from Guest Services fixed that immediately.
The staff are beyond excellent - Abdul we love you and wish you could've come home with us! The place is sparkling clean all the time, everywhere without exception. The food in the buffet was fabulous; the food in the Edelweiss dining room was beyond excellent; Chops Grille was outstanding (OMG the creme brulee on fire was to die for) and the Chef's Table was like we'd died and gone to heaven!
The snorkelling at the Isle of Pines was amazing - definitely go to the left of the sacred rock - forget about the right hand side. Snorkelling at Mystery Island was awesome - walk to the far side of the island and head right towards the tip - reefs right up to the beach - awesome. Lifou snorkelling was absolutely amazing - walk straight up the hill above the little marketplace then turn left at the T intersection until you get to the empty carpark area and then aim diagonally downhill to find a whole bunch of locals set up selling chips and soft drinks, plus hiring out snorkelling gear, and a new set of steps down to the most incredible reefs I have seen (better than Australia sorry guys!).
Port Vila was awesome - we opted to get a taxi to the Holiday Inn (sounds daggy - is the most amazing resort ever love love love) and spent the day swimming, going to the Spa and chilling out.
Noumea was great for shoe shopping and Lemon Bay is awesome. Forget the excursions just buy a $10 Hop on Hop off bus ticket and go everywhere all day. Great cafes opposite Lemon Bay too.
Entertainment was first class every night; the movies were great; the casino was crap unless you like Blackjack and Slots (we don't), the Solarium Pool area was fabulous when it was raining with the big glass roof overhead and even more fabulous with the roof completely open and the perfect blue sky above!
What more can I say - we are booking our next Cruise already! Royal Caribbean get our vote every time. Cost us about $2500 for 11 days plus we only spent $350 between two of us on drinks and gifts which is pretty good even though we had several cocktails every day! Drinks start at about $5 for beer, $6.75 for Torched Cherry Cocktails and wine for about $7 a glass - cheap!
If you want to feel like you're Royalty then do a cruise with RCL - the staff were unbelievable. We loved every minute.
Happy to answer questions if you have specifics.
