The beverage package: You are paying around $20 per person for estimated tips. It entitles you to drinks up to $15. If you go top shelf and exceed $15, then you pay the difference and extra tips. In most cases if you each will drink 2-3 drinks per day it is worth it. If not, you can decline the package. If you search this forum there have been many threads about this subject. I always take the package and am happy with it, others decline, it is all about how many drinks you anticipate enjoying on your vacation.
The dining package is usually for two meals for both passengers. It would be nice to get seven, but not with this package. You can certainly buy additional nights if you wish. $35 bucks is worth 2 nights specialty dining in my opinion.
I try to disconnect on a cruise so I don't have much to say about wifi, wifey uses it to check in with our son, but that is about it.
I would never use the free airfare, as I like to control when we fly and on which airlines, so can't help much there.
$50 shore excursion for one person per port, can't save them up, must use or lose each port. It is free and if you plan on taking an excursion it is a good deal.
If you don't want any of these options you can book sail away prices, but we enjoy the perks and don't do that. When you see the cost difference between the sail away and a room booked with the free at sea options you will see the true cost of the "free" at sea promotion.
No such thing as a free lunch, but in my opinion, we accept the promotion and enjoy the perks.
Hope this helps.
