If you're wanting to get a decent Bali experience we recommend a week before the wedding then a week ish after, so 12-14 days. This will allow you time to experience Indonesia's culture along with the hustle and bustle of Bali's tourism keeping a good amount of 'days on' and 'days off'.
Firstly this is one of the busiest parts of the island, its where all the tourists base themselves and where you can do most of your bargain hunting and shopping. Its nice and close to the airport and a good place to start. Below are some hotel suggestions at different price points that we have personally stayed in!
$ = $50-$80 per night
$$ =$80-$100 per night
$$$ = $100+ per night
$$ Hotel Villa Lumbung (did someone say swim up bar?)
$$$ De Vins Sky Hotel (treat yourself to a whirlpool suite for a night)
Wyndham Taman Sari Jivva We have stayed here and it is BEAUTFIUL! Prices currently range from $108 to $176 per night depending on your preferred level of luxury! We stayed in the cheapest room and it was honestly so nice!
ALWAYS! ALWAYS! ALWAYS! CHECK EXPEDIA FOR BETTER HOTEL PRICES, YOU NEVER KNOW AND YOU ALSO GET PRETTY GOOD DISCOUNTS IF YOU HAVE AN EXPEDIA ACCOUNT :)
