In case you are still looking:
Sign on to the site. On the Welcome Home Page, click on "Help & Contact" in the upper right hand corner. On the next page (called "Help & Contact"), click on the envelope icon under "Contact Us" on the right side. That will give you the email page. Be specific in the message section and make sure you include Travel Plan # for your trip if the request relates to a trip. Also, you mention two different reservations at different times. Would advise that you send separate emails on them for any requests you want. After sending the email, you will get a computer generated, form response that acknowledges receipt of email and that they will get back to you in approximately 5 days. These days it has often taken a week but you will eventually receive another email confirming that the requests you made are incldued with your reservation.
