I have been to Goa practically every year for past 22 years post marriage . please plan to visit South Goa and North Goa separately. North Goa the best place is between Calangute and Baga beach. There are many beach facing properties here Taj Agoda is the costliest . Goa tourism property at Calangute beach (Calangute residency) is giving a try. All sight seeing which is essentially North Goa which is beaches and South Goa which is church plus 2 temples and then some village/house etc.Also try evening cruise at Panaji. Cab service is preferably done at North Goa. If you are newly married do not try hiring bikes because then your wife will tease you as cheapester for rest of life. South Goa is more for relaxing, swimming in beach etc. Leela, ITC etc are great properties. Other slightly lower end properties are Holiday Inn resort, Club Mahindra, Zuri etc. Every resort is good. Regarding AC all beach facing resorts need AC to be on else the humidity makes the floors wet (seriously) .
