Happy Annivarsary!!!
My DH and I are celebrating our 15th annivarsary (a bit late) at Cali grill next month. We are very excited about this. We live on an extreemly tight budget so this is way different than anything we have ever done before. The nicest place we have ever been is Outback, so this is big for us! Plus... we have been together since I was 15, married at 17, first baby at 19... noone thought we'd make it but we just know (sometimes you just know!) So it is great to reach this milestone and LOVE your spouse many times more than even when you first got married!!!
Last year my grandparents had their 50th annivarsary. They decided to drive to DL (from the Detroit area). We did some special things for them that made their trip special. (It is way easier BTW to do this at DW than DL!!!)
We had a basket ordered and delivered to their room. They had some left over stock from DL's 50th annivarsary so they used some of that in their basket. They got golden ears, a 50th celebrations photo album, stuffed bride and groom Mickey and Minnie, among otehr things. It was very customized, you could do that for sure.
We had shirts made with Mickey and Minnie bride and groom and had their dates put on them. They said something like Celebrating 50 years of marriage and 50 years of magic, or something like that. They got lots of compliments on them. We also ordered them the bride and groom ears which they wore proudly.
They had a very nice dinner at Napa Rose (I believe the nicest restaurant in DL)
Now this we didn't do, and you shouldn't assume it will happen to you, but when I made their reservations I told them of their annivarsary (and b-days, they were also within 3 days of both their 70th b-days, they are 8 hours apart) and how they met in 3rd grade and Gpa told Gma at the age of 8 that he would marry her someday and here they are... Anyway, the lady was enjoying the store (it is so sweet) and said she hoped they'd have a wonderful stay. When they arrived they were upgraded to the nicest suite overlooking Cali Adventure--- a $2000 a night room. They were also given lots of other little things, a couple rides alone, whole lines saying happy 50th, flowers in the room, treats delivered by room service. They took such good care of them it was wonderful.
Also, flowers to the room would be wonderful and I would love it if my DH ordered me a castle cake... (wonder how to get him to read this!!!

)
Wahtever you do I am sure it will be special, enjoy!!!
