Anyone ever use a Combi Strolle STS-1 lightweight stroller? I fount one on one step ahead website for less than $50. I am considering getting it. I don't want to spend any more thatn $50 because my 3 yr old son won't hardly sit in a stroller but I feel like we definitely need one for our WDW trip. We will be staying 5 nights and 6 days in August so I know he will tire quickly due to the heat. I know everyone is raving about the Maclaren strollers but I can't make myself spend the money on one considering he won't ride in a stroller much. Thought or input on the Combi Strolle STS-1 lightweight stroller?
