The "rent the cheapest car possible and just leave your luggage in the trunk" is an interesting idea. Admittedly, I have not tried this, but if you are a premium hotel's frequent stay program (gold, platinum, or whatever their levels are these days) you might try leaving your luggage with the bellman at a nicer hotel. They generally will hold it if you arrive prior to your check-in time or you're hanging around after your check-out time ... but if you asked (and added a big tip) they might hold your luggage even if you're not staying there.
The one-stop-shop Glosshouz is a sleek, modern, bright space with the entire spectrum of beauty and spa care available in one place. Whether you need a relaxing full-day escape or a quick pick-me-up, everything is on the menu here: nails, makeup, hair extensions, blow outs, spray tanning and waxing to facials, body treatments, massages, soaking spa and more. Start at the bar, where you can order up a healthy smoothie, glass of bubbly, cup of tea or whatever suits your mood. Then move on to an especially indulgent (but at a great value) spa or beauty package. Try the Benefit Spa Package, which runs two hours and 15 minutes and includes a massage, reflexology for hands and feet, a custom facial and a complimentary beverage.
