Olivia - the Amex tour on PANDA included the officer's mess. It's a mini-version of the tables in La Verandah.
I liked that event - even got to see my laundry on the "to be returned to the rightful owner" rack. The crew did seem pleased we'd come down to appreciate their work and enjoy a drink in their company. Not sure I'd want to do that particular trip every cruise, but nice for a change of pace. Anytime we merit the spontaneous smiles from our crew, it's a good thing IMHO.
Cheers, Anne
