It really depends on the individual. Many of my friends can go to 14,000' from sea level in a day with no ill effects. A few start puking at 8,000'. If you haven't been you will not know.
Many have problems with going to an elevation they are not use to going. Many from SoCal will start to wall out above 11,500'.
I can go to San G on a day with no ill effects but will have a four symptom AMS at 10,000' on an overnight trip, if I do not start taking Diamox three days prior to going.
Again, everyone is different and there are no stock answers.
