I have purchased a double snap'n'go for the twins, but I still have my single snap'n'go from my prior two DC. I've lent it out to several friends and relatives and after my sister finished with it last year, one of the wheels broke off. (She has offered to pay for it and/or replace if necessary. We are really close and these things are just a non-issue.)

I am wondering if it is worth getting it fixed, or if I should look into borrowing someone's, or will there be no need for a single? I can always wait and see, but it is easier to find someone to borrow from earlier rather than later.

Do you find that you are often heading out with just one twin, or is it always with both? If you are ever out with just one, does it seem like overkill to use the double snap'n'go? I have a full time nanny, so it's not like I always have to take all the kids out on my own.
