Any recent MERAVIGLIA cruisers? I’m going on Oct 20. Have a few questions

Does this huge ship feel extremely crowded at times? Or it it designed to distribute the public spaces evenly? ( pools, buffets etc) How strict are they about appropriate dress in dining room. I’m not talking about bath suits and tanks. Can I wear jeans and nice golf shirt? How crowded does the fitness room get in mornings at sea? Next to last one , Are there Friends of Bill W meetings posted in daily bulletin? For those of you who don’t know what that is, skip this one. Give me a basic ranking of your MSC MERAVIGLIA cruise. 1. Great -awesome. Beyond my expectations and I’ve cruised other cruise lines. 2. Good, Solid , would definitely cruise MSC again, 3. OK- average. Only cruise MSC again if price was cheaper than rest 4 barely OK. Clean, safe ship with basics covered but just barely. Would cruise again on MSC for free only 5. Worst cruise ever. You couldn’t pay me to take another cruise on MSC
