Check into 90210-land on the (relative) cheap in two new Beverly Hills redos. The CRESCENT remakes the Beverly Crescent with 40 cozy-sleek rooms and an indoor/outdoor lounge and restaurant (rooms from $150, 310-247-0505, http://www.crescentbh.com). The 49-room MOSAIC remodels the former Beverly Hills Inn with Frette linens, Bulgari toiletries, DSL Internet access, and an international tapas bar (from $225, 310-278-0303, www.mosaichotel.com). Save up to splurge on Rodeo Drive — which is just a short stroll from either.
