I have 2 double strollers (front and back and side by side). Since my girls are 3 and we hardley ever use either I am thinking I want to sell one since they are both in good condition. I would like to keep one maybe for vacations for on the boardwalk or long walks and they may not want to walk or for just in case we need it situations. We also have a wagon. Which do you think would be better to keep. I was thinking the side by side since it seems more comfortable as they seats recline. Only the back seat reclines on the front and back stroller. Thoughts would be great!
