Dolphin is a great and cute creature that also you can see in Bali, Even you can swim and play with them as close as you want, So you will not have to go to lovina beach due to the direction and the location is away from kuta. Dolphin in Lovina beach is a great place you may visit,But if you have only short day (3-4 Days) it is an option to see dolphin at serangan island, Located only 20 Minutes from Kuta tourist center. You will not need to wake up very early in the morning due to dolphin (the wild dolhin) only appear in the morning (8-10 am) and also they appear when there is warm weather (cloudy or rain they are not come to surface).
The dolphin lodging it self is open in 3 scheduled time 10am,1:30pm and 4:30pm, So you may choose the time for your visit. The show will open for 45 minutes and you may come to the see to capture your moment with the dolphin and play with them around. There is not required a swimming since the local instructor/Guard will stay with you during the dolphin attractions.
This is may become a great combination for your memorable holiday in Bali
