I’ve been to STP once, ANE twice, and MIC several times. If the distances are the same, I prefer MIC. ANE had this awesome little FBO the first time I went (put my plane in their hangar for free to thaw the frozen rain off of it) but they got bought out before my second trip and now it doesn’t have much to set it apart from any other delta. STP was great and seemed affordable for an overnight at a bigger delta. Thunderbird at MIC has always been very friendly to me but the last time I was there (March 2021) I found out that the airport commission had changed the standards for fuel farms, Thunderbird has let theirs go, and the airport commission opened their own self serve fuel inconveniently located far from the FBO or any noticeable transient parking.
I’ve never quite justified the cost of MSP yet. Overnights are where I think the most pain would be felt, so if you’re making a day trip it might work out fine. Post your PIREP here when you get home. And good luck!
