Hi! Welcome to the game! Building a ride is a fun yet expensive way to start off your experience on MyVMK. I did the same thing when I came back too. I think the best way to earn credits is POTC right now. HM is good too but not many people wait in the lobby. Jungle Cruise is decent if it's double credits day & you have nobody to play the other 2 games with xD
Ride Tips:
If you plan on making your room automatically put people on the ride make sure your tracks are long enough for each room in case loading items take awhile. Otherwise just have a start so they can get on themselves!
Also another cool thing to add to your ride is height differences on some parts so there's a drop or a climb with pixels underneath supporting these parts. Pixels are 5-50c each and are great for building like that & come in a variety of colors. (I thought the price was 10 but I know it's not above 50).
All ride pieces cost the same so dw about using one type over another.
Make sure to have fun and hopefully release the room(s) when you're done so we can all see it!!
