My family and I will be heading to Disney World and stay at POR 9/9 - 9/17. We are flying Frontier Airlines which seems to have pretty steep baggage fees, especially for all that I need to bring having a toddler and a five year old. I am wanting to ship all of our things: toiletries, diapers, wipes, snacks, shoes, clothes, etc... I know that the recommended way to ship is UPS, and I believe I have found the correct address and know how to address the actual shipping label, but I am wondering if people generally use a UPS store or customer center to ship? I thought I had previously read that it was cheaper to use the customer center and today my MIL called the UPS store and they told her $83 for 23lbs!!! So, I looked online at the customer center and saw that you can't actually go there to ship packages. Is this correct? Any information would be GREATLY appreciated. Thanks in advance!!!
