Frankfurt Airport Question

I am staying at the Hilton Garden Inn at The Squaire at the Frankfurt Airport. I plan to check my bags and pick up my boarding pass the night before my 8:30 AM Singapore Airlines flight. If I leave my hotel at 7:00 AM will that 1 and 1/2 hours of time be sufficent to walk to my gate in Terminal 1 and go though customs, etc.?

Thanks!

Yes, should be fine. Will Sing Air let you check your bags that far in advance?

Yes I can check my bags the night before! But only for that one particular AM flight to JFK.

When you check in the day before I would just double check with them as to what time you should arrive.

I will ask when I check in but I wondered what other peoples' experiences had been.
