I've tried to search the threads, but can't find what I'm looking for...We have a 2 yr old 24 lb DD and a 58 lb 5 1/2 yr old DD. We don't have a stroller for our 5 yo, but I'm thinking we will need a stroller for our older DD to take breaks in after 10-12+ hrs of walking for 7 days in Disney. I don't want side by side b/c she won't be in it much and they take up so much room width-wise. I was thinking of a sit n stand so that we can just push the 2 yr old at least 1/2 the time and then my 5 yo can take breaks as needed. I don't want to rent the double at the park since that would be over $200! I'd rather buy one new for maybe $150 or buy something used that I can sell when I get back. (Haven't had much luck on CL in the last few days...not many options and we're here in Atlanta.) I saw Joovy Caboose with 45 lb weight limit and Sit N Stand with 40 lb weight limit. What about those weight limits? Any advice on any of them? Any other choices? I've heard mention of the boards that can be attached? Do they attach to certain ones-if so which ones? TIA for any and all info!
