We absolutely love our city mini. I rented one for our first trip and by our 2nd trip, I had purchased one because I found it on sale marked down to the point that it was only $15 more to purchase than to rent it (I get the insurance). We do other things like sporting events, zoos, etc so it has gotten a lot of use even though ds was 2 when I got it. I love the size and comfort and the shade, but that it folds with one pull and I can carry it with one hand.
I travel alone with my 2 children and it never fails someone approaches me to help and before theyve gotten the words out Ive folded it with just one pull and am walking onto the bus. It was especially helpful when ds was 10 months old. I could carry it with one hand and wear him in the Ergo carrier. It unfolds just as easily.
I havent decided if it will make the next trip to Disney or not. We're flying and usually that means I'm pulling luggage and my daughter pushes my son in the stroller. Im thinking of relieving dd of her stroller duties and getting her her first personal piece of luggage and having ds walk the airport. So not wanting to rent what I have, Im thinking of renting the GT for our next trip.
