Cruise Suzy

We've been to Aruba before and taken the "introductory" tours. One place we've not been is the Butterfly Farm. Our cruise does offer a 3-hour tour that includes it along with Ayo Rock and Natural Bridge. It also passes the Gold Mill Ruins. We probably want to spend more time at Butterfly Farm than the tour allows. How much time would be the minimum to spend there to fully enjoy it? Are there vendors at the port that might offer transportation to/from the Butterfly Farm? There doesn't seem to be a public bus stop near there.

Have been gifted with OBC which we decided to use for the unlimited laundry package during next week's cruise. Just want to be sure I understand a couple things. 1) When the stewards pick up the bag, I hope they leave another for you to use. Otherwise, we'd have to wait for the bag to be retuned which rather negates the idea. 2) Disembarkation is on Sunday morning. Can laundry be turned in on Friday morning - or is Thursday night the last time to do this? I'm sure the stewards could tell us. We've not had a problem with being able to pack enough clothes as we drive to the port, but it will be nice not to have a lot of laundry to sort/wash/dry/fold as soon as we return. Thanks for input.
