Does sound like a fan issue to me mate, the fact that you said when you were moving again the temp came down makes the point.
The standard fan switch makes the fans come on at about 90-91 degrees, as said let it idle for 10 / 15 mins and the fans should come on, basically when the temp gauge is around the middle.
Be worth checking to make sure water is getting through the radiator, make sure the bottom hose is warm once shes been running for a while.
Im mental paranoid about the cars cooling system so ive been through this a few times
