Not all trips are like this, but a lot are. It's v important to do a lot of digging and sifting (and talking to trip alumni) when choosing to drop that kind of money on a trip. Some trips really are good experience, but as a prevet, the type of experience you can expect is often limited just because you aren't a vet student/vet.
Personally, a trip abroad, even if it were real veterinary experience, doesn't hold a lot of weight with me. I am also not on an adcom.
Basically this. It's kind of a gamble. If you already have quite a lot of hours, a trip may not matter much. On the other hand, if you have very few hours and need to buy your experience, that isn't great either. These trips can be fun ways to get some hands on experience, but they are in no way a realistic portrayal of what 99% of vets are doing on the day to day. I'd rather see someone with 100 hours in a clinic than 100 hours bottle feeding orphaned manatees, even though the latter is more exciting.
