Have used Kingdom Strollers twice and loved, loved, loved them! You do need to check boxes for rain cover and cooler, even though they are free, when ordering. Liked that they had the Citi Mini GT which has a few more inches of head space if you have tall kids. They answered my live chat at 11PM on night one of our trip when I'd rented only a single and needed a double (company I'd gotten the single from had no doubles). They not only answered at 11pm, they went back and put a brand new double stroller together and delivered it at 3am so I'd have it the next morning. Talk about service! Best money we spent. We had no trouble getting it on and off buses. Well worth it when kids were tired. So much easier to push than an umbrella, I could push 100lbs in it one handed and not even difficult. It cost less than one day's park ticket for the whole week. DO IT!
