I know that straws aren't allowed at AK for the safety of the animals, but does that include the sippy cups that have the straws in them? Dd will be 2 on our next trip and I planned on taking her sippy cup to AK since they don't have straws (and I totally understand and agree with the reasoning behind it), but I think that the plastic straw that wont be removed from her sippy cup (she or her brother wont be able to even take off the lid) is different than your typical drinking straw. Would it be ok to take the sippy in or should I just pack the oldest, rattiest shirt she will have and let her drink from a real cup that day? WWYD? TIA
