Honeymoon itinerary: too busy and too much travel?

Hello! Currently planning a honeymoon for November my fiancé and I (31 M and 28 F)We’re currently considering doing Singapore for roughly 4 days, Thailand for 9-10 days(2 days in Bangkok, overnight train to Chiang Mai for 3 days, and Krabi/beach area for 4 days) and the Maldives for 7 days. Flying out of and returning to the Chicago area. We’re used to travel and very busy trips (have done a lot of Italy, a Belgium/amsterdam trip with many stops, Barcelona and the south of Spain, etc). We want a bucket list trip with a mix of adventure and cultural experiences while also getting adequate relaxation time. Does anyone have any advice on if this might be too busy or have any tips/advice? We know it might be better to spend more time in one or two areas to really get the full experience but we want to check off a couple bucket list things, just how we prefer to travel. Thank you so much for any tips!
