I am surprised that they are opening the hotel entrance as it sounds like it'll become a free-for-all in Forbidden Valley. Obviously we don't know what crowd control they'll have in place or indeed what is planned for the actual opening of Nemesis, but I'd have thought they'd have wanted everyone to have entered through the main entrance and walk through the newly installed FV entrance. But it sounds like you'll just walk into FV (from either entrance) and join the queue outside Nemesis (if the queueline isn't open) like you would any other day. On the face of it, it does sound slightly disappointing.
I will be there at 9am and entering through the main gate so I may have to eat my words if it turns out there is some sort of opening ceremony like Sub Terra (I still don't think the leader of the Phalanx is dead and may make an appearance)!!
