There are several ways you can successfully cloth diaper on vacation, but there are things you'll need to consider before deciding what kind of diaper you'd like to use.
1. How long will you be gone?
If it'll only be a couple of days, then you can bring whatever diaper you would normally use (so long as you have enough) without worrying about washing. Our diapers frequently wait a few days before being washed so this shouldn't hurt them in the least.
If you'll be gone longer than a few days and/or you don't have enough to last the entire time you're gone, you'll want to keep reading.
2. Will you have access to a washing machine?
In the case of this question, the asker is unsure if they'll have access to one. If it were me, I would consider going with something that would be simple to handwash and that will also dry quickly when hung.
3. How will you store the dirty diapers and then transport them back home?
You'll need a pail liner/wet bag/hanging wet bag for storage, of course. I prefer the ones that zip because I feel like they hold the smell in longer (especially if you'll have several days worth of diapers in there!). You could also bring your actual pail with liner if you have the space to transport it.
Once you've thought about all of the above items, you'll want to choose the diapers you're going to bring. Ideally, you'll have all of these options to choose from at home already which will make deciding even better. But if you're not a cloth diaper addict like me, lol, you might not. You can buy more, make what you have work, borrow from a cloth diapering friend, etc.
Here's what I would suggest using if you're not sure you'll have access to a washing machine and you'll be gone awhile:
1. flats and covers: They dry fast when hung, they're super easy to wash by hand in a sink.
2. prefolds and covers: Almost as quick and easy to wash and dry by hand as the flats, but more people seem to have these around the house in abundance.
3. Flip and/or Grovia system: You can get both of these systems in a disposable option if you want to go that way, you can use the cloth option, or you can use a combination of both.
A couple of other suggestions:
1. With all of the above options, I would suggest using a fleece liner to protect sensitive skin (but that's because my little man gets red easily in these options and does better with a liner between him and the diaper).
2. Bring samples of laundry detergent with you. They're small so they transport easier. Plus, you'll have them if you come across a washing machine and you can use them to handwash. If you don't have a sample and don't want to order one, you can always premeasure into a small bag.
I hope that adequately answers this question! Good luck on vacation this summer! :D
