Whenever conditions allow, visitors will be permitted on board. Requests may be faxed to Crystal Cruises' Marine Operations department (1.310.277.2465), or if on board, request can be made through the ship's Reception Desk. All requests and supporting information must be received in writing by the Crystal Cruises' Marine Operations Department no later than two weeks prior to the intended visit day. The numbers and types of visitors allowed are capacity controlled and subject to the security level at the port of call. Due to changing world conditions, Crystal Cruises may institute a no-visitor policy on board its ships from time to time. This policy is subject to change, without notice, at any time.
