A big thank you to everyone for your responses! The pictures from allearsnet really helped me decide to just do rentals. Our DD's are 4 and 7. The 4 year old will undoubtedly need a stroller by the end of our ten day stay, and even the seven year old may tire out in the evenings toward the end of our stay. I knew we would need one at least part of the time, but hated to depend on renting one if our 4 yr old wouldn't fit well in them. (Although she is quite small for her age.) After seeing the pictures, I can tell that they will be plenty large enough and I like the idea of renting only when we need them, and not having to lug one around all day just so she'll have one later in the day when she gets tired. Thanks again for all your help!
