Both my sons (5&8) got their first haircuts there and we try to get back every time we visit. For our trip in June we waited a little too long and we were all very shaggy.
About reservations. We tried calling while we were there in June but kept getting routed to dining. So we stopped in - there was a 15 minute wait. I asked about waiting or getting a reservation and here is what the cm hostess told me:
1. If you get a 30-min or less wait, you should stay and wait it out (we did and it was quick)
2. Central reservations only has 2 slots per 30 minute reservation period, the rest are set aside for walk-ins. So even when it is hard to get reservations, it can be quick for walk-ins.
3. You can't make a reservation with the hostess - you have to call and you will likely be offered a time a week from now. If you want something soon, you have to walk-in.
Also, they couldn't take credit cards, if I remember right (maybe it was cash?). Someone ahead of me was having trouble paying - I thought it was with a CC. Magic bands are accepted and cash tips are fine.
Anniegirl, I expect they will cut your hair. I have seen them cut girls hair and they cut men's hair - they don't seem to have restrictions. DW only gets hers cut one place, so I can't say for sure. They are all about the magic!
