Travel system question

Hi Mama’s and Mama’s to be! I just purchased a Graco travel system since it was on amazon for $100 off plus a $5 coupon. We’ll be registering for a shower once we know if we’re having a boy or a girl and my husband thinks we should register for another travel system so we don’t have to switch the strollers back and forth between cars. I kind of feel like it’s not 100% necessary and might even be more of a hassle with two car seats hanging around. I’m a FTM so opinion are welcome!
