Finally got everything booked for 8/15 Alaskan on the Wonder. I had numerous instances of it timing out and/or freezing or the Check Availability button not doing anything at all. So, they were still having some glitches around 11amEST. This itinerary lists Character Breakfast (no mention of which characters), Princess Gathering and Frozen Meet & Greet.
This is what it showed me, when I went back after booking to note the availability:
Character Breakfast was offered on Day 2 (Sea), Day 3 (Tracy Arm), Day 6 (Ketchikan, SOLD OUT) -7:45-9:30 seating every 15 minutes.
Frozen offered on Day 2 - 2-3:15, every 15 minutes
- Day 4 - 4:30- 5:45, every 15 minutes
Princess Offered on Day 2 & Day 3- 11:30- 12:45, every 15 minutes
Note: when I went back afterwards to get the available times for this post, it told me there were no available activities on Day 5 and 7. Which is odd, considering I booked a Princess Gathering for Day 7 earlier...it doesn't say SOLD OUT, like the Character Breakfast on Day 6, it just won't pull up anything. I swear there was a Character Breakfast on this day earlier, as well. So, I'm thinking its still a glitch.
Hope it helps, although I doubt its complete!
