It is probably high time I made one of these lists! I'm sure it's missing tons of stuff, but for now...
Passports - super easy, already had them!
Save the Dates - DIY luggage tag magnets
Flights booked (red-eye, hope we don't regret it!)
Transportation from airport to PDC decided on (public bus, so much info on the web!)
Accommodations booked for half the trip (May 2, 3, & 4, our wedding night)
Photographer booked (Jonathon from del Sol, the absolute most exciting thing about our wedding, aside from the marriage itself!)
Wedding planner selected (Leanne Marie, so happy to have her!)
Amy's ring - ordered online and received it yesterday, but it's too big, so we're exchanging the size
My ring - I've chosen what I want, but waiting to order till I have a better idea on size (currently slimming up)
My dress - chosen, but again, waiting to order till I have a better idea on size (8 weeks order time, so I'll order 12 weeks out)
Bridesmaids dresses - 1 out of 5 ordered, 2 out of 5 selected but not ordered yet, 2 out of 5 not chosen yet (all different styles, obviously)
Bridesman's attire - Amy has a guy friend in the wedding, so his shirt will match the bridesmaids' dresses (he can find white pants on his own)
Invitations - DIY message in a bottle, with a passport booklet of pre-travel info (currently working on them, long way to go)
To be done:
Accommodations for the second half of the trip (only able to stay 2 more days after the wedding, but want a change of scenery)
Amy's dress - aside from browsing dresses over a year ago, she has made no progress on this (hates shopping, hates trying on clothes)
Live music - possibly having a Spanish guitar player & hoping to have a bridesmaid sing in the wedding; looking to combine these two things
Music - ipod reception decided on, but more to go on this (need to book system and speakers & decide on music)
Flowers - have talked to a vendor, but mostly undecided right now (I'm picky and cheap, not the best combo)
Make-up/hair arrangements - very unsure of this right now... want to bring in a pro, but don't think we can afford it (I have chosen a hairstyle, at least)
Ceremony decor - have lots of ideas, working with the wedding planner to execute them, but need to shop for many things
Reception decor - a few ideas, but a long way off from feeling confident about this; lots of decisions to make & shopping to do!
Transportation to/from ceremony and reception - wedding planner is helping with this, I think (need to check)
OOT bags - not planning to go crazy with these, but want to make sure everyone has sunscreen, aloe, and meds
Dog sitter - one of our dogs can be difficult, so trial run(s) not optional; need to get on this!
What else am I forgetting? I should have another look through this thread to see what else there is. Don't want to suddenly remember something too late!
