Recently, The Ghost Train has rarely opened in the morning, It often opens pretty late afternoon about 3-4pm
But if it does open early , I would advise that you do head to it , because the queue will build up pretty quickly.
Since it's a weekend and with it being Summer I would expect it to be relatively busy with max queue times being about 60 mins possibly more for big rides.
The Only News we've gotten about Loggers Leap is that it is Closed for Redevelopment with it being unknown if it will ever reopen. No Work has happened since it closed at the End of 2015.
In Regards to Slammer, Thorpe Park are Saying to " Watch This Space" Which Suggests To me that they will be replacing it with a new ride, most likely another Flat.
London Bridge has been placed on lockdown amid reports of three men carrying knives attacking people and up to 20 have reportedly been struck by a van.
They'll probably be doing safety checks on Rumba tomorrow just like they did with saw when the smiler crashed in 2015.
The park will be closed tomorrow in respect of the family of the girl who died.
