Buy-in In Unique 5-10 Game

I am travelling to Puerto Rico and plan to play some poker there. However, the game as I understand it is a variation on a standard 5-10 game I have never had experience with. It is 5-10, but pflop and all streets can be raised 10 dollars. For example, an UTG raise preflop can make it $15 to go. Has anyone played in a game like this? How would this change my buy in? Also any tips on playing a structure like this couldn't hurt. Thanks.
