You will be fine for a couple hours. I would try and get the carcass cool and out of the wind during the trip, but for just two hours you should not have any meat loss. Ice is not a bad idea, but trying to keep ice in that tempurature never knowing when you will score could be a loosing battle.
I actually gut shot a deer one evening in 80 degree weather. Did not find her till the following night. Took it to the processor afterwards. He smelled the meat and said it would be fine. Tasted great.
Some cultures actually eat meat that is semi-rotting. Not recommended, but you will be fine for the short time you have. Good luck.
