I first came across the sit n stroll travel car seat and holiday buggy when we booked our first family cruise. Anyone who has cruised knows that the cabins can be tight and the thought of filling our room with luggage, car seat and buggy seemed a bit much (you can read more about our advice for which cruise room is best for your family and packing needs here). So we started googling for solutions which is when we first found out about the sit n stroll. The sit n stroll promised to deliver on being a holiday buggy, child airplane seat and car seat. We have now used this system on many short and long haul flights and across several continents so here is what we have to say about the sit n stroll.
