@Fossil If you complete all event activities and the first daily activities every day, then you do get enough for one of the two cheaper companions. But you definitely can't get more than one each week, and you'd have to do a weekly event a couple of times to get the two higher-priced companions.
So big support! I always finish the event activities within the first 24-48 hours and then left a little aimless for the rest of the week after I've collected my daily tickets. I'd like access to more tickets so I could afford the other things on offer instead of just waiting a week to buy a companion, but even if the extra activities didn't provide tickets and just provided pebbles/moonstone shards, then I'd be happy. I just want more things to be working towards each week.
