Yes, you can, but you might be better off paying OOP. CRT dinner for adults is $67 and the HDDR Cat 2 and 3 are $59 and $55. The value of a TS credit is roughly $37.50, so $75 for 2 of them and neither of these makes that mark. Now if you have children, that might make up the difference.
4 nights equals 4 TS credits so you COULD do them - but see the cost analysis above as to whether you'd want to. both of these are fixed price so it won't matter what you order.
