You've completely missed a number of points. First, all Presidents earn and take vacations. You can't criticize any of them merely for that. Second, if frequency were a problem, all of the most frequent Presidential vacationers have been Republicans with Bush-43 proudly leading the way. Third, if vacationing during hard economic times is a problem, you cannot mention Obama's few vacations taken during the recent crisis without noting the 18 trips to Santa Barbara that Reagan took during the course of that also staggering downturn.
The grandfatherly character that Reagan perfected as his on-camera Presidential personna did seem likable. That's about all many people really seem to recall of him though.
He did a horrible job. He took the tail end of an oil supply crisis and through his voodoo supply-side economics turned it into what was then the worst economic disaster since the Great Depression. Unemployment was above 10% for ten straight months. Later came the 1987 stock market crash. He wasted billions (and that was a lot of money in those days) on his hapless Star Wars toy. He sold weapons to Iran and illegally used the proceeds to fund the operation of right-wing Central American death squads. He failed to do anything at all about the AIDS epidemic. In the wake of the Challenger disaster, he sent sensitive missile technology to China. He failed to notice that North Korea was building a major plutonium reactor. Despite all that famous free cheese, he dismantled the social safety net and crippled enviromental efforts. He counted ketchup as a vegetable for the school lunch program and thought trees and Mount St. Helen's created more pollution that American automobiles. If Nancy's astrologer hadn't happened to get a few things right now and then, there's no telling how much damage the man might have done.
