Take condoms with you from the UK as condoms bought in some countries will not be manufactured to as high a standard and are more likely to split or break.
Condoms are freely available to pack in your case and take with you. Come along to a sexual health clinic and pick some up. And if you have sex whilst on holiday don’t leave them in your case…..use them!
Remember to change condom between different sexual activities (oral, vaginal and/or anal sex) and if you use extra lube this should be water based and can improve safety.
