if i am wanting to take advantage of the options of making payments/payment plan for my vacation, how far in advance can i book?
you can book room reservations or plan a magic your way vacation package as far as 499 days in advance. this will allow you to book a room, add tickets, possible dining plans and more, with only a small deposit and a payment plan.
take a cruise from san diego. holland america line travels to mexico for 7 - 10 days from san diego. great food, great prices, and lots of touring in each city they stop in. i just went on the 7-day and i loved it. i got to see puerto vallarta, mazatlan, and cabo. mazatlan was my favorite. so beautiful and cultural. don't go through a travel agent that is going to charge you for their services. most agents are paid from the company they book you with and should not be over charging you for the same thing you could book on your own. they will charge an extra fee for airline reservations just because the airlines do not pay them commissions anymore. if you go on a cruise you can call the company direclty. depending on the hotel, it can take 1 to 8 business days from the end of your stay for the hold to be released and your funds to become available again. you can sign up for automatic account notifications to find out immediately when your money is released: https://www.greendot.com/greendot/account/alert. If the payment book is all you need, then call them and get one. contact your local service provider as early as possible. the decorating season is short, and our schedules tend to fill up by mid-november. 1) add a comment to your reservation that it a birthday is involved. 
2) email/call the gm or concierge and let them know it's fine to do so, in april. however, it needs to be mentioned that driving in iceland in winter might be way more difficult than you expect, even if you have arctic driving experience. about booking accommodation along the way, it does take quite a lot of time on logistics. see if you can spare yourself time by selecting beforehand where you want to be. yes, you can always go early but you just can't go late. once you have accepted a booking, customers will have two hours to pick up the currency that they have ordered at your location. once the two hours are up, the booking will have expired. you should have three choices.

 thanks for the update...i'll check it out. most automated banking payment systems won't have been told deceember 25th is different from any other day. 

the credit may not reach another account until the 27th but if you pay on time, they can't complain. if you're worried about it, pay it on the 24th.
