opinions needed

so i might be getting a couple a really awesome gift to thank them for helping with everything wedding related and apartment related. they did so much that i feel the need to go over board haha

i want to get them a night at a hotel nearby (a W hotel) and a massage for each of them (at the Bliss Spa in teh hotel)... its really ...

so my question is, should i go through with the whole package? or should i just get the massages, and have them stay with us for the night?

OR should i book the hotel room and get them each a gift certificate and if they want to book a better massage, or a different treatment, they have the option to add the money on...?

i wouldn't book a room for them only because you don't know their schedules ... what if you book a date they can't come.

but gift certificates are always nice.

though if you want to go a cheaper route, you can just give them a gc to a nice restaurant
