Bay Club vs. Beach Club
I go to both each year, because each is unique and provides different benefits.
As an owner in the Hilton group I go by points. Only the Bay Club has a one bedroom, so that is usually 4,800 points or 3,400 for a few weeks in May and September(so I prefer that time of year). Size wise think of the Bay Club as a condo size units(yelp) and the Beach club as a TS. If I am going with a bigger group I rent the free standing Bay Club duplex, I think it is 2,000 sq. ft and it has a private covered parking area in front of the duplex; and it is 2,000 points or so less than the Beach Club. This October I am staying at the Beach Club in their premium 2 bedroom unit, even though it is not as large as the Bay Club villa, our group is small and the amenities are those of a premier so I will pay more. But since the Bay Club has been renovated, its not a big point either way. Oh yes, everyone speaks about the Beach Club being free admission to the Hotel Pool, and they are right. But for 15 years my family walks over to the Hotel and we swim in the lagoon and have never been stopped. Just don't carry a Bay Club colored beach towel.
Bottomline, stay at either and have a great time. If you pay by points, the Bay Club is a better value. If you are doing a RCI trade, say a 2 bedroom for a two bedroom and you get the Beach Club, good score. But it is harder because there are fewer Beach Club units. I am glad you did not bring up the Kingsland, because for the amount of points being charged for those units, I would not even consider it.
In my mind, I just want to be in Waikolao, and the first location that I check into since the renovation suits me well. Check out the pictures. By the way, the two resorts share the same check in and are literary 15 feet adjacent to each other and their pools are available to everyone. The hotel pool is the shuttle ride or short walk, and the grounds of the hotel are worth at least one day of your vacation, but for my money that is it. The Big island has a lot of attractions and a swimming pool is nice for a relaxation day. More fun than the hotel pool is to go to the beach and by the way a nice beach is a 10 minute car drive. The beach at the Hilton Hotel is non swimmable. The closest beach is the Marriott 2 blocks away. All beaches in Hawaii are public. But if you want to snorkel, it is worth a short drive say to the Four Seasons or Mauna Kea for a world class beach. I have read the comparisons between the Bay Club and the Beach Club for years and all the talk of the free use of the hotel, but no one ever mentions that fact that hotel pools are not as important as a beautiful beach, and that the Hilton Hotel does not have a safe accessible beach. Just for good measure if you offered me a 2 bedroom Bay Club or a Beach Club for free, I would opt for the Beach Club, but go on ebay and for the same amount of HGVC points the Beach Club costs 6-10x more and no I would not consider that price point differential since I have the same great time at either one, and enjoy spending my points between them.
