Just make sure you are prepared to be driving possibly much longer than 7 hours. Be prepare for winter driving and make sure you have some emergency rations just in case and don't let the gas gage get much below half a tank if possible.
I am up in WNY for the winter. We are having snow now and it really adds to the drving time. Last week I90 was shut for a couple of days due to lake effect snow. We didn't get much on Grand Island but south of here was a nightmare.
You will also need $1.00 for the Grand Island bridge to get to Niagara Falls.
