First of all, talk to Moe. Then, go to the hotel. The entrance is locked, but there is a scaffolding on the left. Climb up and follow studs. Once there, force the door open, destroy the gray object and build color swapper. After you fire green into the lamp in front of the bee figure, it will start to move up and down.
From there, jump onto the balcony, where there is a gym. You have to use each piece of equipment three times to prove that you are a club member. Of course, you have to succeed at each one of the minigames. Enter the room, take dynamite and blow up the lift door.
You have to use the chicken here, to get to the next buildings and reach the hotel. Along your path, you should encounter no difficulties: you can jump onto the roof of the first building off the water jets from the swimming pool, using the chicken.
Finally, you will have to build a swimming pool for 30 000 bricks. Fortunately, Super Bricks can also be found here: one of them is behind the door and visible, whereas the other one can be collected from the corner, after the parasol and the deckchair are destroyed.
Fill the pool with water (using the fire extinguisher) and roll the ball from the center to the right side of the roof, to the opening. You can now bounce off to the catapult (if necessary, use the chicken). In the next roof, use the teleporting device hidden under the boulder.
ON the next rooftop, carry the crate from the right side onto the green brick and build an RC car. Steer the car over to the other end of the roof to destroy the fragment of scaffolding. Use the bricks to build color swapper. Use it and use the teleporting device to return to the previous rooftop, where there is a red button. Launch yourself from the next catapult to reach the location, where you can eavesdrop on conversation between Vinnie and Rex.
