Netgear guest network bandwidth limiter

[2009buddyboy2009]

i have a lot of cousins and step-cousins and friends and step family and relatives and family friends etc that visit all the time (maybe about 1-2 days a month no one is visiting with us.) Relatives and friends are always visiting since my house is on a beach and is very large with 3 spare rooms. Anyway I pay for the best Internet I can get where I live. (75mb/s down and 10mb/s up) anyway I have a family of 5. 2 of the kids are gamers along with me. But when other people are over (especial during summer and Christmas school break we usually have at least 7 cousins over, then not to mention when the kids have their friends over) I put all guests/friends on the guest network and me and my household family on the main network. The router is a netgear n600. Is there someway I can limit the guest network bandwidth with the router gui to let's say 30mb/s? PLEASE HELP I want MY Internet to be fast and not allow the guests to use ALL of MY hard earned bandwidth!!! I have already enabled QoS for my Direct family and lowered all the guests QoS to low. ANY suggestions will be appreciated
