Negotiating Funding

[Kingace]

Hi, I have received an offer from a school I really would like to go to but the funding is half of what I am getting at other schools. While I don't desperately need the additional money and could always ask my parents for financial support, I obviously would prefer receiving more money from the school and not having to do that. I also feel like I'm not as wanted since the funding is less. How should I phrase it if I were to ask them to try and revise my offer to be in line with my other offers?

What about schools with a line such as this one in their offer: "Please note that if you are in possession of more favourable offers from other distinguished departments, I would be happy to discuss our offer further." How should one phrase it then?
