Vehicle entry fee for national parks

We will be traveling in Uganda in a private vehicle. I am wondering whether the entry fee for vehicles for Ugandan National Parks are valid across different parks and for an indefinite period of time. I know that for QENP it costs$150 for the vehicle, a one fee for the whole time, and then pay separately for the entrance fee, which is per day. It will make a big difference to our planning if we know that we could pay $150 for the whole trip and/or if we find out we have to pay this fee in each park we want to go to.
Thanks for any input!

Vehicle entry fees depend on the type of the Vehicle you will be travelling in.

For every park, you have got to pay vehicle and park entry fees.

I thought you must have made a mistake about the amount so checked out the UWA website. These fees are new since we were there in April/May. Then it was about $40 for a 4WD from memory. $150 is prohibitive. I fear the fee will be per park. That's certainly how it worked when we were there - albeit with the cheaper fee.

I agree with itchyfeet38. $150 is for trace passing not Vehicle entry fees.
4x4 wheel safari vehicle costs about 25$ and it is paid once for every park you enter.
