Worth depends on who you ask.
If you are talking money, can you afford the extra cost without worrying if it will leave you enough for your food and souvie budget?
If you are talking space, does your group need the extra tv and bathroom? Maybe someone has a headache and would like to be in a quiet room (bedroom) away from everyone else. Having a single room would make this impossible. Maybe you have a baby that needs a nap or part of your group goes to bed early and the rest are night owls. I know my husband is a tv hog. I like the idea of an extra tv. The extra bathroom is ideal for getting ready for the day, especially if a member of your group seems to take a day and a half primping.
Just some things to think about.
The other option is 2 of the other rooms. Your quote seems to be a bit cheaper than the suite. It would give you everything the suite would, except the couch and separate shower, but you would then have more beds, bigger 2nd bathroom, etc.
