I am debating what to do about strollers for our trip in April. DD will be 7 months and we will be picking up a lightweight stroller that will recline instead of using her travel system jogging stroller . When we went last April DD3 and DD5 rode in the double stroller we rented at the park (at the time they were 2 and 4). Is DD5 too old for a stroller? Instead of spending the $16 a day to rent, should I buy a double stroller that I won't use again? Any recommendations of what kind of strollers to buy?
