Thomas and I have really enjoyed receiving postcards from others visiting the parks so we would like to return the favor to the first five who reply with: 1. name 2. favorite character 3. address 4. date of visit 5. Special info, such as birthday trip? I could also send out maps to an additional 5. But I have another question. Is there anywhere at DL I can buy stamps and mail these postcards and maps? Also, what size are the maps so I can have the proper size envelopes with me?
