You first have to recruit Manaphy and do a couple of jobs. A few days later Manaphy will wake you up and tell you about Marine Resort.
the marine resort is west of sunyshore
After Manaphy tells you after a couple missions then you can go to the Marine Resort.
beat darkrai and recruit manaphy three days later he will tell you about marine resort
Marine Resort has 19 floors, and on the 19th floor, you can obtain boxes for Xatu Appraisal, and then you go onto a warp tile to exit.
To go to the Marine Resort, you have to beat the entire game (all 20 Chapters), and defeat Darkrai. After that, complete three missions (Sentry Duty might not work), and Manaphy will return. Let him join your team, and then do two missions. When you begin walking towards Treasure Town, Manaphy will tell you about the Marine Resort.
Why woudn't anybody answer this question?Anyways,to unlock Marine Resort in Sky is the same way as in time,when Manaphy comes back,do a few missions and Manaphy will tell you about Marine Resort then you cna go there.
