You can also ask at the hostess table if they can up your reservation from 3 to 5 as long as you are aware that the answer many be no.
THE QUESTION OF AN EXTRA PERSON or EXTRA PEOPLE (the "411"):
1) Disney is getting wise to the "but, they decided to join us" or "I miscounted".
2) People can't always get the ADR they want.
3) So, they under-count to get a table.
4) Then, they show up with "unexpected" additional people.
5) In a team meeting, CM's have been told to warn guests against this.
6)
If there is room, WDW will not turn away revenue.
7)
But, if busy, they will turn away the additions.
8) Go ahead and arrive with the extras, if you like.
9) Just be prepared to have someone stand around while you eat.
10) I have heard explanations such as . . .
. . . "but, Aunt Suzy decided to join us and we need an extra seat"
. . . "but, two friends from off-site decided to join us and we need extra seats"
. . . "but, brother-in-law decided to join us and we need an extra seat"
. . . "but, the entire Boy Scout Troop decided to join us and we need 14 extra sets"
. . . "but, my baby is so small that I didn't count her in the number of eaters"
.
NOTE1: It is far easier going from an odd-number to an even number, such as from 7-people to 8-people, adding a person to an even number of diners, such as going from 6-people to 7-people. Adding odd person can mean adding a table, and this might not be possible. Going from an odd-to-even might only mean adding a chair or using an empty seat. So, if going from even-to-odd, you might not get the extra person a seat. It is always better to get another ADR with the proper people-count.
.
NOTE2: Frequently a party-of-two will try to add a third person at the podium. This can be risky, because many eateries do have tables-for-two. If the guest was slated for one of these, there simply might not be a table available to seat the third person - even if an infant. The extra chair location might extend into an aisle and block access for other guests or Servers.
.
NOTE3: Sometimes there is a threesome adding a fourth. Unfortunately, there are many eateries that do have 3-top tables - usually against a wall or pillar. They can't add a fourth chair, since that would invade the aisle and be unsafe for SERVERS.
! We have an ADR for 3 at Kona for our upcoming trip. We recently found out that friends of ours from home will be at WDW when we are and we would like them to join us for dinner. I keep looking, but so far there aren't any available ADRs for 5 for the time we need. I thought I read somewhere about open bar seating at Kona. Can anyone confirm this? Thanks
