MJ,
ABD has a hotel where they will book you if you book a pre-night through them. In general, ABD's prices are much higher than you can book yourself, but includes transportation from the airport to the hotel, breakfast and transportation to the AMAViola. (GORGEOUS ship!!!) I can't help you with the hotel for Munich, because I did the Budapest to Passau route, and then added on Prague, so I didn't go to Munich at all. You can call ABD and find out what hotel they use, get a price quote, and if you don't like it, book it yourself. If they run it the way they ran it in Budapest, you'll meet at that hotel in the morning, and get all your information about the transfer to the ship later in the day. But you'd best make sure you can take that transport if you don't book the pre-day with them. I really just don't know because I booked the pre-day through ABD since it was an early booking bonus for ABD Insiders (people who have taken at least one ABD already).
As far as the airfare is concerned, ABD Air does not do group airfare bookings like
DCL does. They don't have fixed flights/prices they offer you and you get whatever they give you. It's basically just like booking through a
Travel Agent. You can either have them research & offer you a flight/price, which you have them book if you like it, or you can find the exact flight/price you want, contact them, and have them book it for you. If it's still available, they'll get it for you. I booked my China ABD through ABD air, and they actually found the exact flight I wanted for far less than the lowest price I'd found. They also found a flight for me last summer for the Danube River cruise that was way below anything I found. There has been a lot of debate here whether it's worth booking through ABD, but the biggest advantage is that if ABD has to cancel your trip & reschedule you (doesn't happen much, but it *does* happen on rare occasion) they handle all the (reasonable) costs of changing your flights on their end, and you don't have to worry about changing it yourself, worrying about getting reimbursed, etc. Also, airlines change your flights a lot these days, and I always get a notification from ABD when they do. I've been really happy with booking my airfare through ABD.
Let me or any of us know if you have any questions about this cruise or ABD in general! A lot of us took it last summer (which is probably why you don't see as much discussion of it this year as you do on the Christmas Market cruise).
It's a fabulous trip! You're going to *love* it!!
