Variable Product vs Variable Subscription

I’m am trying to add a product that has a few different payment options and I’m not sure how to proceed. Let me explain what I’m trying to do to see if it’s possible with WooCommerce Subscriptions plugin.

The product is for a retreat where people can book a room, but each room is a different price. I’ve added the Lodging Attribute and added the different rooms as the Variations. Now for the tricky part that I’m struggling with… people have the option to book their spot and pay $500 now and then pay the remaining balance in increments. But, they also have the option to pay in full now and if they do they’ll receive $200 off the total package.

Do I make the product a Variable Product or a Variable Subscription? I’m thinking Subscription so they have the option to make payments, but then what do I do if they want to book the whole thing now to receive the discount? I’m also thinking I could do a coupon so people can receive the $200 off. I think I’ve figured out how to do both options, but not sure how to marry the two within the product.

Does anyone have any suggestions? Any help would be appreciated. Thanks so much!
