It really depends on what you want to do and how you want to skirt the rules. If you are just wearing nice clothes, and happen to have a local officiant stop by for a few words with you, then it shouldn't be a big issue. But if you show up in tux/dress, want music, flower petal carpet etc, then they will but a stop to that. But it all needs to be low key, and not interfere with any guests on property.
Depending on what time you wanted to do it, you may be able to schedule a photo session with their event photographers for afterwards while you are still all dressed up. Or you can usually find a local photographer to come out and work with you, but that will often depend on your timing as they won't be able to use anything outside of the camera mounted flash, and may have issues with dusk/nighttime shots coming out well.
Any TS restaurant should be able to provide you a 6" cake with no notice, but a bigger fancier cake would need to be handled in advance. And only certain TS will be able to do the bigger cakes, it depends on what that resort has for pastry service. Lots of the nice ones come from the GF bakery, so if you end up eating at a restaurant there you should be ok.
If you try to find locals willing to work with you on the down low I imagine that you would be looking at maybe $100 for the officiant, and maybe $150-250 for a photographer. Then whatever dinner and your cake costs you. It would be a bit cheaper.
I'm not sure of your faith, and am not trying to be offensive, but you could get your daughter ordained by the Universal Life Church for free online, pay a few dollars for the official certificate, and then have her take your picture afterwards? That would cost you next to nothing, and would let her be involved in a special event.
