Well I don't have a double stroller, however I can help you with your request on wanting a stroller that isn't bulky. We have a Combi stroller and it is lightweight and easy to fold up, easy to carry, and is easy to maneuver and compact. I've had 2 Combi's and I love them and wouldn't buy anything else! They do make a double stroller (side by side and the other one where one child sits behind the other one). You might want to look at BabyCenter.com for reviews from people who actually own the double strollers and hear their comments on pros and cons on each one of them. I have hand and arm problems and I'm very weak, so I had to do a lot of research and testing out the strollers to have something that was lightweight. I tried all the strollers out at Babies R Us and a speciality children's store that had strollers (harder to find ones). The Combi was the lightest and the easiest to fold up also. It also has a carrying strap where you can carry it on your shoulder. I'm sure you could check out Just Between Friends (Consignment Sale) or on Ebay for some good used strollers. Good Luck!
