Greyhound

Hello All, First, thanks to Matt for great info. We are taking RC Ovation of the Seas next August-- Alaska cruise. Any tips or recommendations would be appreciated. Matt suggests buying the unvlimited drink package, which is now $65. My question is how much does RC charge per drink? Trying to see whether the package or buying drinks a la carte makes more sense. Any dining recommendations? Any other info about the ship would be appreciated.
