So I was on for 8 am and finally got the week of the 28th for Oct. after looking it over and talking with the family we decided we can add a couple more days to our vacation since we didn't get the first weekend. So we will stay 10 nights so we can over lap our vacation with family members that will be there the week of the 4th. So my question is, when can I add my next day? right now I'm booked at 7 mos., the 28th to the 4th. When can I book the 4th - 7th. Can I add at least one night tomorrow? or do I have to wait to April 4th? and if I can do it tomorrow can I do it on line? This is all new to me, I never booked like this before. Thanks for all the help.
