I have stayed at both the Sheraton on the Park and the Four Points and I agree with Dave

.
The Sheraton on the Park is a far nicer property. Currently they are running some good promos for stays with breakfast for 2 included and access to health club/spa/pool and parking (which you may not need) for around $259 per night ( I think its called Summer escape, or surprise IIRC). Its a great property. I loved it ^.
I have had good stays at Four Points, and been upgraded to water front suites which are nice. However it doesnt have a pool and the dining options are not as nice IMHO. Four points deal like above is similar but cheaper at around $220 per night with inclusions. OOPS hope this doesnt sound too much like an SPG advert....I dont work for them

Congrats on the wedding and have a great honeymoon :-:.
