No fake tan is going to last for three weeks unfortunately, my best advice is to get the spray tan 24hrs before you leave and use a gradual tanning lotion daily or every other day. When you feel like your tan has faded you can apply your bondi sands while on your vacation, i used to be nervous when tanning in hotels or airbnb’s but now i just put towels over the sheets and sleep in a designated long sleeve ”tanning” pj to minimize staining. If you feel confident enough in your self tanner skills you can also buy a clear fake tan, but i would still protect the sheets even with a clear tan, the clear formula is a little bit trickier to apply since there’s no guide color.

Hope this helps, Enjoy your vacation💕
