Balloon 68
Opposite the Malibu Club in southern Vice Point is a big water tower. South of this is a small hotel. The balloon is on the east-facing side of the hotel.
Unique Jump 23
Just south of the Malibu Club there's a ramp. Grab a PCJ-600 from the apartment just south of the Pay 'n' Spray in Vice Point then head back and get a good run up from the bridge to the south. Use the crouch technique to get enough speed up to clear the roof of the club into the parking lot behind it.

Takeover the business to the north.
Balloon 69
North of the business is an apartment block. In the center of the block is an open area with basketball courts. The balloon can be seen on the south-west corner of the apartments from the center of the block.
