Bob Duallie or Rent a City Mini Double?

[AllThingsFigment]

We have a bob revolution duallie stroller but I am wondering if we would be better off renting a city mini double for our trip. For those of you that have used double bobs in the parks did you have any problems? On our last trip we had a b agile double and were very happy with it but we no longer have it for this trip. I would prefer to use the bob instead of renting but I'm worried that it might be too big. I'm pretty sure we won't be using the buses so that won't be an issue for us. I thought about just using our single stroller but I know our 3 year old will need to use the stroller as well for afternoon naps and in the evening.

Any pros and cons of either would be great.
