We will be staying at the Poly Conceirge in August for 4 nights with our children ages 7, 5, and 2. I've read on these boards about the possibility of borrowing a stroller from the conceirge if it's available. For those of you who have done this, were you worried about what would happen if the stroller was stolen in the parks? I read you have to put a $250 deposit down and I think I would worry the whole time about it being stolen.
