travel stroller recommendations

Wondering what the best travel stroller is for our situation. I am a first time mom and we have a three month old travelling to Vancouver for a week at the end of the month. We will be doing some leisurely nature type travelling. We already have a uppababy cruz as well as an uppababy aria two car seat

We will be bringing our car seat with us. Just wondering what the best travel stroller would be in the situation. Hopefully we will be travelling more. Do I really need car seat adaptability so should I stay within the uppababy ecosystem? The minu seems fairly bulky. Or should I buy something else like a bugaboo butterfly 2? We want something as portable and streamlined as possible. Any suggestions appreciated.
