Chose this cruise because we did the same cruise 10 years earlier and were anxious to return to Antarctica. The Explorer carries 148 passengers; our earlier trip was on Endeavor, which carried 105. Chose Lindblad Expeditions because we were so pleased with the earlier cruise and we were not disappointed with this one. We liked the informality; no dressing up or coats and ties required. Breakfast and lunch is buffet but guests are invited to order something specially prepared if they prefer. Dinners are served and seating is open, which gives passengers the opportunity to meet each other. Meat, fish, and vegetarian entrees available every day. Alcoholic beverages are not included except at Captain's cocktail reception, farewell cocktail party, and special dinners in a private dining room with ship's naturalists, historians, or photographer. The fitness center is well equipped and there's nothing like walking the treadmill while the ship navigates sea ice! Kayaking, cruising in the Zodiacs, and walks among the penguin colonies are handled efficiently, with emphasis on safety. Educational talks by scientists, naturalists, and historians on board bring meaning to the experience. Very good trip!
