The only benefit worth anything is playoff priority and you can buy into that this time next year if the team is doing better. The Red Carpet Rewards prizes aren't worth the price of the plan, neither are the plan holder events. If those things really matter, find an existing group and buy a small share.
May not work for you but some people value the SPH events (Hot Stove luncheon, fan photo day, etc.) and the RCR points that give you extra tickets, merchandise, etc. Also, access to special events like concerts (Eagles/James Taylor and Zach Brown this year) in addition to playoff and opening day priority. Also, some people just like having set seats and games so they are encouraged to go on a regular basis. I also like the camaraderie that's developed in our ticket groups. You can get much of this stuff by joining a group but I'm a control freak so I like to run my groups.
This above may not be of value to everyone and I understand that.
