Benign paroxysmal positional vertigo (BPPV). BPPV occurs when calcium crystals in your inner ear â which help control your balance â are dislodged from their normal position and move elsewhere in the inner ear. BPPV is the most common cause of vertigo. You might experience a spinning sensation when turning in bed or tilting your head back to look up.
And though we delve into detailed pricing info later on, it's worth noting that the cost of a swim spa is often half that of a standard swimming pool. On average, you can expect to pay $8,900 to $23,000 for a swim spa versus $21,000 to $45,000 for a swimming pool (not including the deck).
What You'll Pay: Cruise line spas charge rates equal to high-end salons, and you may be shocked by the prices. A massage is typically about $120 to $180, with more exotic treatments running into the $200 to $500 range. Passes to thermal suites and thalassotherapy pools average $20 to $30 per day, with cruiselong packages also available. Beware of sales pitches: Most shipboard spas are operated by Steiner's of London, and the staff (who work on commission) often give you the hard sell to persuade you to buy their pricey products.
