Thank you everyone for your replies. We decided to just haul our Sit N Stand because we have found it is not too bad pushing it around with two of our kids in it and the bench seat comfortably seats my DS9 who is on the autism spectrum, is only 48lbs, and has low tone issues with his legs which makes it hard for him to walk for long periods of time. Our DD4 still fits comfortably in the front seat of the Sit N Stand, so that will work for her. Also, the Sit N Stand has a nice storage basket underneath which we will need since the Maclaren one is very small. We are still bringing the Maclaren Triumph for DS2 since he is so attached to that stroller. We originally didn't want to haul the Sit N Stand, but I guess that is the trade off we will have to have in order to avoid spending $$$ on another stroller we really don't need to buy or have the discomfort for both us and DD4 by trying to stroll her around in a cheap stroller she is too big for.
