I would definitely call and confirm! I rented a double city mini from apple and had absolutely no issues w them (I called to confirm about a week before we left but reserved it about 6 months out w credit card and received email confirmation back when I booked confirming everything. My sister on the other hand also reserved a double from apple and received a call the DAY before we were checking in and said they ran out if strollers and there was nothing they could do for her! She also confirmed about a week ahead of time as she never received any kind of email confirmation and was told she was all set. Pretty crappy as she has 3 kids 3, 6, and 8! Every other stroller company was booked up w that short notice to!
