We are going to Toronto with my oldest, she is five and a half, flying private. We don't really need a seat on the plane, but since space will be at a premium we may have to use one. The Toronto traffic scares the crap out of me. She is in a booster seat full time, but is still within the limits of her Frontier. Would you take a booster, or use her Frontier, and use it while seated on the plane? We will be having a private driver, I believe in an SUV, or possibly a van, but the start of this trip will be in a limo, I know that in her seat, of any kind she needs to face the front of the limo. Any ideas of how to do this? We will be doing a lot of shopping while there, and walking would you take a light weight stroller for her, since she has short legs, and doesn't really enjoy walking long distances a lot. I have a Peg stroller, that folds down nicely, and that she will fit into fine. We are also doing Canada Wonderland while we are there.
