Standard view GVs are very limited, two for sure possibly three. Because of the conversion of a standard view GV to Ulu Cafe we think DVC converted an ocean view GV to a standard.
There are more ocean view GVs, but they are still not numerous--17 or 18 (depending on if DVC converted one to a Standard view). You do have a chance, people sometimes book a grand villa just in case the family will vacation at Aulani and later cancel as family members back out.
Good luck!
