Thailand + Bali trip

about to go on my honeymoon. we hadn't traveled since before the pandemic so we wanted to do an all-out adventure. I like exploring new places, she likes luxury and resort-type travel. so this is the itinerary I made.

​

• fly to Bangkok 2 days
• Koh Phayam - 3 days
• Phuket - 4 days
• Singapore for 2 days
• Bali - Seminyak - 2 days
• Bali - Ubud - 6 days

​

I know I'm rushing a bit for some of these places but overall does this look doable? are there any obvious?

also, I'm mostly staying in Seminyak around new Year because I hear potato head has an awesome nye party. would I still be able to reach it and cab back afterward if I stayed somewhere like Uluwatu at one of the resorts instead? or should I stick to Seminyak?
