it was a Africa Twin you saw ;-).
Actually we had no problems with entering through the main gate or any other check points.
As long as you have a valid ticket it is no problem at all.
They just did not let us in any more, after our ticket was expired, although it should be allowed to use the roads inside. Without a valid ticket you just can´t walk inside the temples any more.
There are actually some ways, entries where there are no check points ;-)
Have fun in the temples and if you need some insider tips....
