You can keep on using the ticket.
On your first visit to Loch Ness, you can win a rowboat ticket by playing darts at the Pub (to the right of the Loch).
When you have the submarine ticket, click on the sub (enter) and he will ask for your ticket.
you have to go to the pub and beat the man who doesn't belive in Nessie at darts
The Cryptids Museum is on the first floor of the Mews mansion, to the right.
All you do is go over to the 2nd trash can at the VERY bottom it is there. Good Luck!
The ticket window is closed, so you go to the right, to the Pub. There you will play darts for the boat ticket. When you have a photo of Nessie's "loops," take it back to the Mews lab.

Go on the submarine. You have a ticket. Dive to the bottom and then go left to see a Nessie face in the darkness. Take a photo and go back to the pub with it.
There are two players you have to beat. The first one, with the mustache, has the rowboat ticket. Once you get the photo on the rowboat, you return to Mews. When you go back to Loch Ness, you play the man who has the submarine ticket. Get the photo and bring it back to the pub. You will now play the first player again.
The rowboat is first, then the submarine. You can only win a rowboat ticket on your first visit to Loch Ness, but you will get a photo to take back to Mews. When you go there a second time, you can win a submarine ticket, and you must show the submarine photo you get to the men back at the pub.
Before you can get a ticket for the submarine at Loch Ness, you have to take the first photo (Nessie loops) back to Mews. Then you can return and play darts against the other 2 players to win a sub ticket. Once you have the submarine photo, take it back to the Pub (taking it to Mews is no help at all).
You win at darts a second time and get a submarine ticket.
