forumWhat families say

Rakuten Travel rating 4.09 out of 5 (179 reviews). Families traveling with a baby under 1 report that the staff were kind and the food was delicious. Guests staying with a 4-year-old also report being satisfied with the buffet format, since they could serve only as much as their child would eat and there was little food left over. On the other hand, some guests report that the reception staff at the breakfast venue came across as overbearing, suggesting that service can vary from one staff member to another.
