Hi Stroller Parents! My husband and I are in the process of purchasing a sit-n-stand stroller, and we're hoping it might work for our next Disney trip. Our kids are ages 3.5 and 11mo. We are considering the Baby Trend Deluxe Sit-n-Stand that acts as a regular double stroller but can convert to a Sit-n-Stand. I've really done my homework but still have a couple questions/reservations: 1. How easy is it to convert to the Sit-n-Stand? Can you do it on the go or do you have to set it up before leaving home? 2. Does the "jumpseat" have a cover? I've read reviews that older models just came with the plastic seat. 3. Will a 3.5 year old (average size) fit in either/both seats comfortably? I don't want to pay the extra for the deluxe and then end up only using it as a sit-n-stand. 4. Are both canopies removable? Thanks for any info. you can provide!!
