I have a salt scrub booked at the spa next week (on Carnival). This sounds dumb, but the thing that makes me most nervous about spa treatments is not knowing what to do or wear. If you have had one, can you talk me through what it will be like - what do I wear, do they give me a robe, do I leave undergarments on, am I on a table with a sheet like a massage, etc? I do know they will try to sell me products afterwards so I’m prepared for that LOL. Thank you!
