Oh, you will have so much fun on your cruise! DH and I just returned today from our land/sea vacation!
As for the drinks, I'm not sure how much help this will be but here's what our experience was. We got refillable mugs while at WDW and definitely got our money's worth out of them. On the Wonder, since we booked with
AAA we received two free refillable mugs to use throughout the cruise. I don't think we used them half as much as the ones at the resort. They were good to have on the day at
Castaway Cay, though, because I think that's when we used them the most. I believe we only had them filled twice on the ship other than Castaway Cay where we must have gone to the bar about four times to have them filled.
Since we didn't have to purchase sodas, I didn't really notice how much it cost to buy them. I can tell you that sodas are free with dinner so you could always get your fill of soda at that time if you didn't want to buy the mugs or purchase a lot of sodas at other times.
As for the mixed drinks, I had two during the cruise and I believe they averaged around $4.50-$4.75. Maybe the other more experienced cruisers can confirm that as the average price. I noticed in the navigators that there would be a drink special of the day for about $3.50, though.
Sorry this is so long... I hope it helps some! Good luck with your planning and have a wonderfully magical cruise!
