Go to your dashboard. Select the reservation you want to modify. Then click on the button, VIEW OR MODIFY DETAILS. Then click on the Modify link next to Guest Information. There you will find options to add Adult Guests and also one to add Child guests. Thank you I can get to the reservation through my points usage but the details button is all that came up and when I clicked it there were the contract details no modify came up! Where do you go to get to the reservation is it another place ?
