I understand from a colleague that you are now not allowed to receive parcels from outside into Pennys bay except for medicines. Mind you she is Philippina so they may have different regulations for different nationalities.
So pack a big case with supplies for 14 days. If the quarantine hotels are anything to go by the food at PB will be inedible. The woman above reported PB meals of fried mushroom and baak choi. Go vegan or go home.
