It's always good to go to Longwood, even in the winter on a dreary day!
Actually, the Paph display wasn't very good, there were few of them and they weren't very interesting - I posted the most interesting ones.
They're having an "Orchid Extravaganza" through March 31st with an "International Orchid Show & Sale" on March 28th-30th, hosted by SEPOS. This last is basically an orchid show put on by SEPOS. I went last year and it's definitely worth attending if you live close enough to make a reasonable trip.
"Orchid Extravaganza" seems to mean that they place orchids throughout the Conservatory rather than just in the orchid room. However, these placements seemed to be mostly odd uses of Phalaenopsis in strange arrangements, and they didn't do much for me. They had a pretty large "orchid wall", though, which was interesting.
Columns in tree fern gallery topped with arrangements featuring white Phalaenopsis.
