Ok, I have to ask...how does someone accumulate over 23 million lifetime visitors yet remain permanently at level 24?? This person has been on the leaderboard for quite some time and it baffles me. I'm at level 27 and only have 378,185 lifetime visitors.
The whole attendance deal has me baffled too. I've done searches around the internet in the past to see if anybody has published any secrets to improving attendance and have yet to ever find anything.
I haven't noticed any significant difference in how fast my attendance increases in relation to if my happiness is at 96% or 97% or 98% or 99%.
I'm currently level 46 with 6,081,000 in attendance to date.
I check in on the game often during the hours that I am awake so my happiness rarely goes under 97% unless i'm being lazy and only checking in once an hour letting it drop to 96% each time in the process. While I'm sleeping my happiness can drop into the low 80s, but I really don't notice the pace of new visitors decreasing despite the big drop off in happiness.
I have noticed my attendance building up faster as I've progressed in the game. I attribute this to me adding more attractions and more decorations. There has been times where I've been stuck in a certain range (like 95th - 98th overall in attendance) then I'll add an attraction and suddenly a day or two later I've jumped to like 90th or better.
I've also spent spare gems on the extra decorations so my park has at least one of every possible decoration placed.
But having more attractions and more decorations doesn't explain how somebody can be at level 24 and have 23 million attendance. Unless maybe their park is full of fountains and statues and other key decorations like that. Maybe I should spend some of my 5.5 million magic on a bunch of Ode to Seamstresses, 15-layer Cakes, Coronian Sun Dials, and Minnie Tea Sets and see if my attendance starts to soar.
Maybe some day we'll have a more clear idea of how different things correlate to park attendance.
