We went there last bank holiday [25/5]. Still very closed then and no signs of future developement.
Very sad, but it has been for sale for some while and they can't survive on the minimal custom from passing yachties.
Last I heard the MoD were still finding a new tenant. One with a big pile of cash is required as it was very very tatty. Ring the Mod on the Havengore Bridge number and ask them.
