We were there on 12/22, 23, 24, 25, and 26. (Partial days on 12/22 & 26). We got
Genie+ for our 3 full days.
I couldn't figure out how to cancel a LL on Android. Also, we had a LL for Incredicoaster but it went down so it converted to a multi-attraction. The multi-pass never went away and stayed on our phones all day. (My son has an iPhone, we all share the same account)
We also had an issue with holding a LL for Indiana Jones but the ride went down. It never converted to a multi-attraction LL so we were stuck not able to pick a new one or ride something in it's place. But it was the busiest part of the day so we didn't want to stand in line for 30-40 for Pirates or Jungle Cruise (we rode it before our IJ return time). So we ended up walking to Star Tours only to be told that we should cancel the LL to book the next one. We went back and hung out by Indie and it came back up at the end of our return time.
Another thing I noticed was I picked a LL for Incredicoaster at a time it was down, the return time was about 90 minutes away. We went and did something else and the next time I looked our return time had been extended by 30 more minutes, I guess because it was down.
We didn't go super hard on trying to get multiple attractions each day and having LL was handy. It was nice to get a short return time for Space Mountain and Haunted Mansion after being at DCA for most of the day. We had a return time for Matterhorn one night at 10:30 but they had closed LL return for the night already.
We were previously pros at using both paper fast pass and Max Pass. We felt that Genie was clunky and difficult to use. I didn't use any of the extra features like the Genie suggesting things for us to do. And at least twice I went through all the motions of reserving the next LL attraction and the next time I looked it wasn't there. I swear I did all the steps and saw our confirmed return time, who knows what happened.
We did not do any ILL during our trip. We waited 2 hours for ROTR one night, it had broken down but thankfully we stayed in line (it was raining so were just fine with just being dry for a bit). The second time we rode ROTR it was during the mid-morning and the estimated wait time was 1.5 hours and we waited 1 hour 45 minutes. We rode RSR once, it was quoted for 85 minutes but we waited 1 hour 45 minutes. I understand ROTR being on the ILL and if someone only had one day I would definitely suggest they pay the $20 to guarantee a ride. But I do miss RSR being on the fast pass/Max Pass option. So we rode it once in 5 days instead of 2 or 3. We didn't ride Web Slingers at all, we rode it once in October during the OBB but we wouldn't spend an hour waiting for it, we just didn't enjoy it THAT much.
