I have received summer internship offers for two locations within the same company. One offer is roughly 2.3x the salary of the other, but I would prefer to work with the people at the lower paying location. Personally I don't care about the money, but my parents are paying for a large fraction of my tuition and I know they certainly care about my summer earnings. How can I negotiate this effectively? In particular I would really appreciate advice on how to word the email to the internship coordinator (or perhaps a phone call is better?). Should I contact the HR people at both locations, or only the location that I want to work at?
