Dixit is also a good fit! It is a very easily explained game, where you have to say a word or short phrase describing a mystery card. The rest then places a card they think that matches the description as well, and then a voting round starts. It is really fun, and playing it would do more justice than this explanation :p
Since you are on vacation and might not be able to find some of the other suggestions I will mention Liar's Dice, also known as Perudo. If you can't find an official copy all you need is 5 dice per player (so 30 dice for 6 for example) and some cups or other way to hide the dice rolls.
Ready Set Bet is definitely something I'd love to try, are the side bets or VIP cards simple? My only fear is that I'd have to spend a lot of time explaining those cards to everyone
Captain Sonar requires too much communication to work, it's impossible. Some people only speak portuguese, other only german, not everyone speaks english....
I already own Sushi Go (not party), I think it's an OK game and didn't want to get the party version.
Camel Up is a great suggestion, someone in my regular group owns it already so I might just borrow it!
Both Railroad Ink. and Number 9 (might be called 0-9) are games which are solely component limited, meaning that if you buy 2 boxes you can play with twice the amount of players (12 and 8 respectively).
Mysterium is a co-op game for up to 7 players.
If you are into deduction and quick thinking Ricochet Robots might be for you.
If you want a chill game to have a chat while playing Concept (without the rules for points) is a fun "guess the word/phrase" game.
Concept might work well. The cards are going to have a concept that you try to get other people guess by pointing at a board with various symbols on it. The word for the concept you're trying to get people to guess should be easily translated with a phone, or just skipped and draw a new card.
Rhino Hero is great, especially if there's kids or drunk adults in the group. Kind of like Jenga, try to build up a card tower without knocking it over.
Similarly, Pinnacle's pretty good. Competitive block stacking with weird shapes
Some easy games are Ligretto, Halli Galli and Jungle Speed. Not exactly board games and a very specific category that might not suit everybody, but definitely fun.
Are all fun language independent easy to learn party games that work for 2-8 or 4-12 players.
No word based games
Does that also include other clue giving games such as the following?
Top Ten
Monikers/Times Up
Concept
I feel like they're different enough to justify getting them and they're extremely funny, especially the first three. Top Ten has cards that are open information and can be translated so out of those it would be the best fit, the other ones are language dependent.
